Смысл: The text explains a mathematical and programmatic method to simulate Gouraud shading (smooth lighting) in an HTML5 Canvas 3D engine by creatively using linear gradients to approximate vertex-based color interpolation.
The author implements Gouraud shading in a JS 3D engine by solving linear equations to map vertex colors to HTML5 Canvas linear gradients.
Смысл: The text is a pedagogical guide designed to teach the fundamental mathematics and algorithmic logic behind filling triangles and basic lighting in computer graphics, specifically focusing on the transition from wireframes to solid shaded models.
A tutorial on implementing triangle rasterization, flat shading, and back-face culling to create a basic 3D renderer.
Смысл: The main idea is to demonstrate a practical, mathematically simple approach to simulating iridescence in real-time graphics by linking the viewing angle to the hue of a color model, while also sharing an efficient method for scalable GUI rendering.
A technical guide on simulating the color-shifting effect of a beetle's shell using GLSL shaders and the HSV color model, including a bonus technique for DPI-independent GUI rendering.
