Tīmeklis2016. gada 26. janv. · It seems to me that you should be using an orthographic projection for both the tile map and the ball. Change your reshape function to simply call enable2D (w, h). Then change your drawTiles function to draw using screen coordinates instead. That should work. Some additional notes: Tīmeklislambert factor = max(0.707, 0) = 0.707. OpenGL ES 2’s shading language has built in support for some of these functions so we don’t need to do all of the math by hand, …

Tīmeklis2024. gada 12. apr. · 由于我们在卷积环境贴图时事先不知道视角方向,因此 Epic Games 假设视角方向——也就是镜面反射方向——总是等于输出采样方向ωo,以作进一步近似。OpenGL 可以启用 GL_TEXTURE_CUBE_MAP_SEAMLESS,以为我们提供在立方体贴图的面之间进行正确过滤的选项。我们已经进行了大量的采样,但是在某些环境下 ... I'm working on a ray tracer using C++ and OpenGL (glDrawPixels), and it is going well so far. However, my shading seems to be a bit off. I want my spheres to look a little smoother without having the blatant lines between intensities. At the moment, I am just trying to implement Lambertian shading, which is Intensity = Id * pd * (N dot L). burgess hill christmas market
