When I saw the below demo I thought “neat, how’d they do that”? That may sound surprising if you knew that I wrote the API for this. In this article I’ll describe […]

Importing Blender object normal maps with permutations
We used a lot of object normal maps in RadialBlitz. Figuring out how Blender encoded these was part of the challenge. It didn’t seem to be documented anywhere, nor was I able […]
Stuffing curves into boxes: calculating the bounds
Now that we’ve drawn beziers and arcs there’s only one piece missing in the vector API. We need to calculate the bounds of the curve: the minimum/maximum points where it will draw. […]
Rendering an SVG elliptical arc as bezier curves
I needed to draw ellipses and arcs. A vector API just wouldn’t be complete without them. Though opinions seem to differ as Apple’s Core Graphics lacks anything but an axis aligned circular […]
The smooth sexy curves of a bezier spline
I’ve been dreaming and coding curves lately. They play an integral role in a vector drawing API, which I’m writing for Fuse now. “Bezier curves” are so common we might think it’s […]
Smoothing 3d geometry, like a tunnel, with Catmull-Rom splines
An endless tunnel is the centerpiece of my game Radial Blitz. Flying smoothly through this tunnel was important to me. That required both a smooth tunnel and a smooth camera. In this […]
What is a normal map? An object normal map?
Normal maps preserve the lighting fidelity of a high polygon count model when it is reduced to a lower polygon count. Model designers tend to work with models that are far too […]
