forge-procedural-geometry

Procedural 3D shapes for GPU rendering are generated by calling parametric functions like forge_shapes_sphere(32, 16). This produces geometry in a struct-of-arrays layout, enabling fast iteration of shapes without manual mesh creation for efficient GPU upload.

The struct-of-arrays layout used for procedural geometry buffers separates vertex attributes into individual continuous memory blocks. This format enables efficient GPU upload by allowing direct binding of position, normal, and other attribute buffers in a single render pass across multiple shapes.

Set up forge_shapes.h to generate parametric shapes in a C project by defining FORGE_SHAPES_IMPLEMENTATION in exactly one .c file. This single implementation paradigm enforces a clear workflow for binding vertex buffers and drawing ready-to-render geometry.

You can create multiple parametric shapes like spheres, capsules, cylinders, cones, tori, planes, cubes, and icospheres for real-time graphics demos. The included example snippets demonstrate binding vertex buffers to render these shapes in a single render pass.

Defining FORGE_SHAPES_IMPLEMENTATION in only one C file enforces a single implementation paradigm per project. This prevents duplicate symbol errors during compilation while still allowing other source files to access the procedural shape generation function declarations through the header.

This procedural geometry generation approach works without external dependencies as a standalone header library. It provides clear buffer binding and drawing workflows to output ready-to-render parametric shapes directly within your existing graphics pipeline.
