Detailed Description

Core rendering settings (MSAA, Buffers, Feature Flags).

Macro Definition Documentation

USE_TRANSPARENT_BILLBOARDS

#define USE_TRANSPARENT_BILLBOARDS

Enable High Quality Transparent Sphere Rendering.

If Defined:

• Spheres are rendered as Transparent billboards (GL_BLEND enabled).
• Requires CPU-side sorting (Back-to-Front) every frame in app_render().
• Uses sphere_sorting.c module.
• Alpha channel allows true see-through glass effects.

If Undefined (Legacy/Fast Calculation):

• Spheres are rendered as Opaque (GL_DEPTH_TEST enabled, Write enabled).
• No sorting required (Fast).
• Alpha channel is hijacked to store Luminance for FXAA optimization.

Enumeration Type Documentation

anonymous enum

anonymous enum

Multisample Anti-Aliasing (MSAA) sample count.

Used in app_init() to configure the GLFW window buffer.

• 1: No MSAA (Aliased, fastest).
• 4: Standard Quality.
• 8 or 16: High Quality (Costly).

Note

Only affects the main framebuffer (forward rendering geometry). Does not affect offscreen buffers (Post-Process, IBL) which are single-sampled.

static

Value for all bits enabled in a stencil mask.
