Summary

Introduces GSplatStreams class to centralize texture management for GSplat resources, replacing manual texture map handling across resource classes.

Changes

New GSplatStreams Class

• Manages texture creation, storage, and destruction for GSplat resources
• Provides textureDimensions (Vec2) for consistent texture sizing
• Exposes createTexture(), evalTextureSize(), getTexture(), and destroy() methods

Resource Classes Refactored

• GSplatResourceBase: Now uses GSplatStreams instance instead of manual textures Map
• GSplatContainer, GSplatResource, GSplatCompressedResource: Use streams.init() for texture creation
• GSplatSogResource: Manually sets textureDimensions from loaded texture dimensions (SOG textures are externally owned)

Shader Chunks Updated

• texture sampling now uses injected load function, avoiding manual uniform management
