Functions
LoadedModel	createGlowSphere (int stacks=32, int slices=32, float radius=1.0f, glm::vec3 emissiveColor={10.0f, 6.0f, 2.0f})
	Generate a procedural UV sphere as a LoadedModel with a bright emissive material suitable for testing bloom / HDR glow.

Detailed Description

Procedural UV sphere with emissive material for bloom testing.

Function Documentation

createGlowSphere()

LoadedModel createGlowSphere ( int  stacks = 32, int  slices = 32, float  radius = 1.0f, glm::vec3  emissiveColor = {10.0f, 6.0f, 2.0f}  )

inline

Generate a procedural UV sphere as a LoadedModel with a bright emissive material suitable for testing bloom / HDR glow.

The sphere is centred at the origin with the given radius. Its material uses a high emissiveFactor (well above luminance 1.0) so the bloom downsample pass extracts the glow automatically. A 1×1 white texture is included as the emissive map to prevent the PBR shader from multiplying the factor by the black fallback texture.

Parameters

stacks	Number of latitude subdivisions (default 32).
slices	Number of longitude subdivisions (default 32).
radius	Sphere radius in world units (default 1.0).
emissiveColor	HDR emissive colour (values > 1 trigger bloom).

Returns

A ready-to-upload LoadedModel.
