forge-instanced-rendering

What problem does it solve?

Instanced rendering allows drawing many copies of the same mesh with a single draw call by streaming per-instance transforms.

Core Features & Use Cases

• Per-instance data: a 64-byte model matrix stored for each instance.
• Dual-vertex buffer pipeline: one buffer for per-vertex data and one for per-instance transforms.
• Seven vertex attributes including per-instance matrix columns and per-vertex attributes.
• Vertex shader reconstruction of the model matrix from per-instance data and rendering via a shared VP matrix.
• Use cases include forests, crowds, particle systems, buildings, or any scene with repeated geometry.

Quick Start

Create an array of InstanceData with a 64-byte model matrix for each instance, upload it as a per-instance buffer, and issue a single instanced draw.
