I'm trying to understand mipmapping.
It makes sense that you would have many pictures of your textures at different resolutions, and use the closest ones in size to what you need in order to avoid ...

I'm looking for an effect similar to this image. Assuming the UV coordinates of the triangle are known, such as:
p0 = [0, 0]
p1 = [1, 0]
p2 = [0, 1]
I know the ...

In film school, in the classes of 3D modeling, I was told that when we model something for films we maintain topology of 4 edged polygons. Any polygon which has more or less than 4 edge/vertex is ...

When rendering 3D scenes with transformations applied to the objects, normals have to be transformed with the transposed inverse of the model view matrix. So, with a normal $n$, modelViewMatrix $M$, ...

I read "A Practical Model for Subsurface Light Transport" and "A Rapid Hierarchical Rendering Technique for Translucent Materials". If I understand correctly, the former does not consider the case ...

sRGB is often contrasted with "linear RGB."
Images are stored on disk and passed to displays in sRGB, which is approximately perceptually uniform in intensity.
Shader math is done in linear RGB, ...

The 2D pipeline involves with the construction of world coordinate scene followed by converting world coordinate to viewing coordinate, then transforming viewing coordinate to normalized coordinate ...

That it compresses the data compared to the pixel array is obvious.
But what makes it different from from normal compression (like png, jpeg)?

I implemented a physically based path tracer after studying PBRT by M. Pharr and G. Humphreys. Now I'm trying to apply physically based rendering to real time graphics using OpenGL ES (in an iPhone ...
