| | '''OpenGL extension KHR.texture_compression_astc_hdr |
| | |
| | This module customises the behaviour of the |
| | OpenGL.raw.GL.KHR.texture_compression_astc_hdr to provide a more |
| | Python-friendly API |
| | |
| | Overview (from the spec) |
| | |
| | Adaptive Scalable Texture Compression (ASTC) is a new texture |
| | compression technology that offers unprecendented flexibility, |
| | while producing better or comparable results than existing texture |
| | compressions at all bit rates. It includes support for 2D and |
| | slice-based 3D textures, with low and high dynamic range, at |
| | bitrates from below 1 bit/pixel up to 8 bits/pixel in fine steps. |
| | |
| | The goal of this extension is to support the full 2D profile of the |
| | ASTC texture compression specification, and allow construction of |
| | 3D textures from multiple 2D slices. |
| | |
| | ASTC-compressed textures are handled in OpenGL ES and OpenGL by |
| | adding new supported formats to the existing mechanisms for handling |
| | compressed textures. |
| | |
