Detailed Description

Runtime data for efficiently accessing items within a generated texture atlas.

After a texture atlas is created and processed, this structure provides the information needed to find and render individual items from the packed atlas texture. It maps unique item IDs to their rectangular regions within each layer of the atlas.

Runtime Usage:

ezTextureAtlasRuntimeDesc atlas;
atlas.Load("MyAtlas.ezAtlas");
 
// Find an item by ID
auto item = atlas.m_Items.Find(itemID);
if (item.IsValid())
{
  // Get UV coordinates for diffuse layer (layer 0)
  ezRectU32 rect = item.Value().m_LayerRects[0];
  // Convert to UV coordinates based on atlas texture size
}
