Demo of bilinear interpolation of SDF samples:
- Negative (interior) samples of the analytic SDF are blue, positive (exterior) samples are orange.
- Circles are drawn around samples to show distance magnitude.
- Intermediate bilinear interp samples / segments are drawn.

Probably the most common newb shader mistake is ignoring aspect ratio:
vec2 coord = fragCoord / resolution * 2.0 - 1.0;
Instead of:
vec2 coord = (fragCoord*2.0 - resolution) / resolution.y;
vec2 coord = fragCoord / resolution * 2.0 - 1.0;
Instead of:
vec2 coord = (fragCoord*2.0 - resolution) / resolution.y;

Visual Studio's Memory Layout visualiser is a nice way to detect misalignment issues between C++ and HLSL buffers, in this particular case for a structured buffer, where XMMATRIX is 16-byte aligned, while in HLSL it will be a float4x4 with 4-byte alignment, causing errors.

The drawing and annotation tools in Radical Pie are finished! Now, I can type an equation and add highlighting, arrows, labels, etc., as shown in the following examples. All drawing objects are attached to anchor points in the equation, so they move and resize dynamically.

This video is great for teaching the basics of GJK. However, the approach is flawed for computing distance and only works for determining separation true/false. Unfortunately the author has disabled comments and people keep using this and ending up with broken code. www.youtube.com/watch?v=Qupq...

Spherical harmonics are widely used in graphics. Ever wondered how to compute their derivatives? My HPG 2025 poster shows that it is basically free.
It also comes with a code generator for C, C++, Python, GLSL and HLSL to compute SH with derivatives.

Decided to check out how water is rendered in Counter-Strike 2.
Given how interactive water in CS2 is, I expected to see some cellular fluid simulation, but turns out they just use a low-resolution off-screen buffer with flat 2D decals used for various aspects of water. Reminds me of HL2 water :)
