So far, this project is an attempt at a basic 2D / 3D graphics framework / engine in Odin.

• Learn Odin.
• Understand what's required for creating a basic graphics engine:
  • How should pipelines be specified in a way that is both flexible and convenient?
  • How should the vertex format in a model be connected to the vertex format of the pipeline?

The RenderBatch system provides an efficient GPU rendering pipeline by organizing draw operations into discrete units of work. Each RenderBatch encapsulates the essential components needed for a single GPU draw call:

• A Vulkan pipeline configuration
• Texture mappings (connecting texture handles to descriptor indices)
• Mesh data (vertices and indices)
• Uniform data (planned)

During frame preparation, the system converts front-end draw commands (boxes, textured quads, glyphs) into individual batches using a temporary allocator. These batches are recreated each frame.

The rendering process for each batch follows a standard sequence:

1. Pipeline binding
2. Descriptor set updates for textures
3. Mesh data binding
4. Draw call execution

The system includes a texture registry that enables texture sharing across multiple batches. Textures can be:

• Registered into the system
• Loaded from files
• Updated from bitmap data

Current texture lookup is performed by searching the registry using texture handles.
