#Textures & UV Mapping

Load textures from glTF files, sample them in the fragment shader, and add UV coordinates to the vertex format.

#What Was Delivered

• UV coordinates (TEXCOORD_0) extracted from glTF and generated for all procedural primitives
• Base color texture loading from glTF (embedded GLB and external URI)
• Per-material descriptor set (set 1) with COMBINED_IMAGE_SAMPLER
• 1x1 white fallback texture for untextured meshes
• Fragment shader: texture(baseColorTex, fragUV).rgb * vertexColor before Blinn-Phong lighting
• PNG/JPEG decoding via stb_image
