    Projective texture mapping for projectors with lens shift

    Oh, I'm late but maybe I can help someone who has the same question. In computer graphics, the problem is called off-axis projection; see here for...

    How to Aim Animator.SetIKRotation() to direction WRT hand bone rotation offset?

    I'm working on a workaround based on the observation that the difference between the specified goal orientation and the actual goal orientation in...

    How to Aim Animator.SetIKRotation() to direction WRT hand bone rotation offset?

    I don't think this is a valid answer: the documentation of SetIKRotation states...

    Render at half resolution, upsample to full resolution

    Wow, I haven't been here for a while. :) Not necessarily. About 7 years ago, I looked into finding an efficient algorithm. I think it's still...

    Are all Blend combinations equal in performance costs?

    I wouldn't be surprised because once blending is enabled in traditional fixed-function hardware, the data might be (computed and) transferred in...

    Why could we have more than one forwardbase pass in a shader

    My first thought would be depth priming.

    Initial values for variables in CG shader not being set

    Just tested it. Apparently, I was wrong and the initialization of uniforms doesn't matter at all. (Even if there is no property defined for it;...

    Initial values for variables in CG shader not being set

    I might be wrong, but I think it depends on the material: once you have a material associated with a shader, it is the material that specifies the...

    ZTest Less vs. ZTest LEqual for one-pass rendering

    I cannot test anything now, but I would assume that the "common circumstance" where it matters is when you use the exact same geometry in both...

    How to combine color with texture while not affecting whites blacks

    You can also use Tags { "Queue"="Transparent+2" } or Tags { "Queue"="Transparent+3" } etc. for shaders that are even further in front. An...

    Possible to Make Shader that Renders at Intersections with Another Mesh?

    The more general problem is known as CSG (constructive solid geometry). Google for GPU-based implementations of CSG and you will find a couple of...

    Update vertex colors in script and show it through shader.

    I think Lerp expects a third argument between 0 and 1. Time.time will usually be greater than 1; thus, this is probably clamped to 1 which then...
