Lets say you have a function that evaluates a location in spherical coordinates, and gives you the offset from a sphere surface that the point exists on. In my case...
Lets say you have a single point on a surface, and you want to get its normal. The surface is generated procedurally. What would be the proper way to get...
If you have an animation that transitions from one color to another, what's the ideal color space to do this, where the color in the middle of the transition will...
I'm trying to ray trace a sphere in a fragment shader. The fragment shader is essentially happening on a 2d plane. The vertexes of this plane have been transformed in...
I'm trying to use some obj files downloaded from the web for assets. In the faces section of the file, some of the faces look like: ``` f 25/25/25 23/23/23...
Is there a recommendation for picking RGB values from a scalar value?
In the section4 recitation slide, it shows breaking out matrix A into sections that correspond to free/constrained variables: What parts of matrix A correspond to `Acf` and `Afc`?
I'm not sure really how to go from: to: If there was no A, it could be done like (Where Gt = G transposed): `GtGs=Gtu` Are there any examples out...
I remember the professor mentioning something in class, that how we build the matrix for the homework would slightly different than how it was defined in the [class slides for...
If we have a normal vector, and want to build a transformation matrix that rotates something by the direction of a normal vector, how do we setup that transformation matrix?
