Context

  • Added partial texture updates for image, CPR, reslice, and volume rendering.
  • Improved 16-bit scalar accuracy by using filterable 32-bit float textures when required and supported.
  • Added mipmaps for supported 2D RGBA images to reduce minification artifacts.
  • Enabled transfer-function texture sharing and improved texture-allocation caching.
  • Fixed image array slice selection and hardware picking.
  • Added regression tests for texture updates, scalar formats, mipmaps, and caching.
