hello-cube

Overview ¶

Command hello-cube renders a lit, rotating cube using g3d + gogpu.

This is the "hello world" of g3d -- a minimal example that demonstrates:

• Scene graph setup (scene, mesh, lights, camera)
• PBR material with functional options
• Forward renderer with depth testing
• dt-based animation (smooth on any refresh rate)
• Window resize handling (aspect ratio + depth buffer)
• Proper GPU resource lifecycle (defer Release)

Run with different backends:

GOGPU_GRAPHICS_API=vulkan   go run .
GOGPU_GRAPHICS_API=dx12     go run .
GOGPU_GRAPHICS_API=gles     go run .
GOGPU_GRAPHICS_API=software go run .
