| | | | | Rectangular Bezier Patches are one way to bring Bezier curves into the 3rd dimension as a Bezier surface. Below is a rendered image of a quadratic Bezier rectangle (degree of (2,2)) and a cubic Bezier rectangle (degree of (3,3)) taken as screenshots from a shadertoy demo I created that renders these in real time.

| | | | | There's an interactive Bezier Triangles webGL demo I made that goes with this post, and what i used to make the 3d rendered images with. You can find here: http://demofox.org/BezierTriangle.html https://demofox2.files.wordpress.com/2019/12/cubicbeziertriangle.png Above is a cubic bezier triangle which has 10 control points. Each edge of the triangle is a cubic Bezier. That makes for 9... | |

| | | | | This is an extension of a paper I wrote which shows how to use the linear texture sampling capabilities of the GPU to calculate points on Bezier curves. You store the control points in the texture, then sample along the texture's diagonal to get points on the curve: GPU Texture Sampler Bezier Curve Evaluation I've... | |

| | | This is a "soft tech" post. If that isn't your thing, don't worry, I'll be returning to some cool "hard tech" and interesting algorithms after this. I've been abusing the heck out of the GPU texture sampler lately, so be on the lookout for some posts on that soon (; I'm about to show you... | ||
