Line of sight is the real magic… Skyboxes work all by themselves! In fact, if you printed 6 photographic images and arranged them as a cube, and then stood on a stool so that your head was positioned at the centre, you’d then be looking at a 360-degree view of the world. The optical principles explained and demonstrated throughout this tutorial, also apply to game engines such as Unity and Unreal Engine, and therefore OpenGL is just one of any number of graphics APIs to which they apply. Sky-spheres are optically equivalent to skyboxes, which means standing at the centre of a sphere looks exactly the same as when standing at the centre of a cube. Fullscreen quad! Indeed… it’s perfectly possible (programmatically) to display a sky-world by rendering a full-screen quad and calculating the direction vectors of the view frustum in object space. In computer graphics, although camera lens distortion doesn’t occur when rasterising the geometry of primitives such as triangles – perspective distortion (AKA field of view distortion) does occur. Here’s a great article which talks about different types of lens and perspective distortions: 🤍 Visit 🤍 to acquire all the source code for each OpenGL Quick Start tutorial episode.

I decided 2 months ago to finally make that plunge towards modern OpenGL after spending over a year and a half on SFML 2d Graphics. This was and is probably the most difficult API to understand. Libraries used to complement 3.3.0 core profile are GLFW3, GLAD, GLM, ImGui, and STB image. Precompiled headers were also used to speed up compile times. This is an example of a galaxy Nebula skybox + a ground grid texture running on CodeBlocks x64 20.03 running openGL version 330 core profile. This incorporates a 4k exr galaxy image converted to png file format then converted again to 6 cube faces to be sampled using samplerCube for a skybox environment. (Note: I don't mean the video is in 4k, the actual image is in 4k for better skybox detail) The ground object is a cube as well just scaled down and wide accordingly to resemble the floor. Texture is a simple png grid from Photoshop with GL_REPEAT for a grid-like appearance. The texture coordinates are also within the vertex buffer and defined in the Vertex shader along with rgba values which are then both sent to the Fragment shader to be used via uniform sampler2D. This results in an interpolated color range + a grid texture without alpha blending. The glGenerateMipmap() function was manually set to prevent excess blurriness at large distances. Without this the far horizon would look too jagged and results in an artifact mess. However by not setting it manually it becomes TOO blurry. I should incorporate anisotropic filtering but that requires OpenGL 4.6 I believe. Other things included here are camera matrix transformations for freelook with mouse events, middle mouse button event, WSAD keyboard events using GLFW3 and ImGui library for data info and docking feature. Framebuffer size callback also changes on window resizing, and vertex buffer vertices size was reduced by re-using the same vertices and using index buffer (GL_ELEMENT_ARRAY_BUFFER) for both ground object and cubemap. The 4k cubemap seems to really make a difference. I've tested with lower resolutions with 1024 and 2048 pixels. The latter would be the minimum for background detail but as you go up the loading times get a bit longer. (On 4k image cubemaps initial loading takes several seconds more) Using desktop i9-9900k + RTX 3090 Founders Edition. Need to implement lighting by including Phong shader model using ambient, diffusion, and specular then revisiting this. Once I get that down I'd like to move on to spherical objects and then hopefully physics and particles again. I miss tinkering with particles so much!
Parallax Corrected Cubemaps is a new feature, developed by our Lead Programmer Dominic, which allows for more accurate reflections to be projected onto surfaces. The basic explanation is that it allows level designers to define the boundaries of a room and project a very accurate display of the room and its contents onto the surfaces within the room; which also allows the reflections to stay in their proper location while the player moves around the room.

This wasn't at all what I expected. Felt closer than I actually was to achieve shadow mapping of point lights: - Oh, you just use a CubeMap. It will be just as easy. Clearly I did not know what I was up against. As some one put it nicely in stack-overflow: 🤍 "Cube Maps have been specified to follow the RenderMan specification (for whatever reason), and RenderMan assumes the images' origin being in the upper left, contrary to the usual OpenGL behaviour of having the image origin in the lower left. That's why things get swapped in the Y direction. It totally breaks with the usual OpenGL semantics and doesn't make sense at all. But now we're stuck with it." Next adventure, fix the shadow-acne.. it will be easy... :D Have fun!
After going through phyically based rendering tutorial on learnopengl.com, I decided to extend the feature to make the reflected image look more correct. The result was satisfying. 🤍
Honestly, the more I listen to myself speaking, the more I wince at the thought of me spamming "uhh..." and "you know" over 9000 per minute. Guess I still have a long way to go before I improve. Did some work on our college graphics project today. This has been one of the more fun projects to work on, although most of the code being available beforehand on learnopengl.com has certainly lowered the entry barrier. Excellent, excellent site, never thought love working with graphics to this extent, but here I am. Wallpaper found on 4chan, hopefully that rules out any copyright issues. Thanks anon.

My latest game Cavian requires me to render into a dynamic cubemap so I created these demos while I was developing a pipeline in my engine. The code is done in OpenGL and C, the rest is my own work. The skybox was from google somewhere and the meshes are made by me. Hope you enjoy the overly dramatic music
In this video, we look into 3D textures, or cubemaps. We go through the entire process of generating one, inserting images, and rendering it.

This is a basic beach scene I created in C/GLSL (OpenGL) for a Computer Graphics assignment. It is complete with a skybox (cube map texture), objects with reflective surfaces (cube, sphere, torus, and cylinder primitives), and lighting using the Phong shading model. ~ The skybox is a cube map texture of an HDR image that comes from the Humus website: 🤍 The one I used is titled "San Francisco 4". I implemented Phong shading by programming and adding diffuse, ambient, and specular light components. Basically, I assign material characteristics to objects when I create them in the driver program; then in the fragment shader I manipulate the color depending on the effect I want the object to have (for example, reflective objects have different effects than non reflective objects). I use that new color to calculate the diffuse and ambient components. Finally I add them together with the specular component and the result is the directional light (out variable). To create the skybox and reflective objects, I use the cube map texture in the fragment shader (mirrored for reflective objects). ~ The background ocean sound comes from this video: 🤍 ~ If you read this far, here is a sneak peek at my next personal project: I am going to try to recreate the court room setting of Danganronpa in OpenGL, and include sprites of the characters! However, before I can do that, I must finish the final project for my 3D Modeling/Animation class and all my exams which all occur on 9 and 10 December! I will upload my 3D modeling final project if it comes out well enough. ~ This was for Assignment #7 (the final assignment) in my CS 4722: Computer Graphics and Multimedia class at KSU. It was due 8 December 2021 at 11:59 PM. #ComputerGraphics #OpenGL

In this tutorial we will take a look at the 3 thing in the title -Cubemap is 6 texture arranged as a cube, we can use for skyboxes or for cubemap-reflections, cubemap-refractions -Shiny surfaces reflect their surroundings, we can easily model this with a cubemap and a vector expressed in world space (we get it by the reflect function) -When light goes through in transparent objects it slightly changes the path, it's called refraction (like magnifying glass), we can model this effect by a cubemap and the refract function (again in world space) Source: 🤍
Trying to create a reflection in OpenGL / C using programmable shaders with GLSL to control graphics processing, vertex buffer objects to get a high polygon mesh stored in video ram and multiple dynamic cube maps for the reflection, the skybox is a static cube map. The mesh is created as a grid of tiles and is deformed by the vertex shader at render time using a sin wave type function and normals are generated here per vertex, the reflection vector is calculated in 'view space' using the interpolated fragment position and fragment normal and is used as a texture lookup into the associated cubemap. There is a visual inaccuracy that I sort of expected to happen, the map is rendered from the centre of each tile but the fragments are offset, so their perspective on the scene is different. this is running at around 40 frames per second on a 8800GT card, there are a few optimizations that i can make for example the chessboards are computed on cpu then sent to the graphics card about 100 times per frame, but they could be stored once in a VBO, the framebuffer image is copied into a texture many times per frame but the texture object can be used directly as the color buffer instead. Have tested the polygon density rendering once per frame it can go up to about 200k of triangles before affecting the performance. The image at the end is a section of my desktop background its a screenshot from a game.

Uses Lancellotti chapel cubemap for reflection, refraction and image based lighting. I admit the IBL doesn't look that good. I used ModifiedCubeMapGen but I have to learn how to use it better.
A dynamic reflection created by rendering the scene to a cube map in a frame buffer. That cube map is then passed to the sphere as the texture use for reflections. Problems: 6 additional render passes per reflective object in order to build cube map. Non-square frame buffer causing problems.

This builds upon my previous video with the addition of cube maps built using C and OpenGL Shading Language. Link to my GitHub repository: 🤍 Looks alright, in my opinion. The shadow map acne on some on the curved objects is a nuisance, but that's about it for gripes.
This is another graphic demo that demonstrates dynamic cubemapping. Dynamic cubemapping allowes for a number of effects to an object such as dynamic environment mapping and dynamic refracting which allows for an object to be see through to some extent. This particular implementation I'm demonstrating is quite expensive because it requires 7 passes to produce the effect which is very expensive. There is a work around in later version of OpenGL and Direct3D 10 above that can do this type of mapping in 1 pass which is something I'll explore in a later date, but to be honest the only thing that I might use this technique for is to make convincing water for my scenes. I'll probably redo the water demo to use this technique to make very convincing water next time around. The next demo will cover parallax occupation which is a technique to fake depth in a flat surface, this should be a fun one to play with.
