|
| 7 |
|
| 8 | The components here are being shared with the Khronos community to provide
|
| 9 | early insights into the specification of XGL and to assists those doing
|
| 10 | prototyping at this point.
|
| JensOwen | 786bcc6 | 2014-11-01 09:28:29 -0600 | [diff] [blame] | 11 |
|
| 12 | The following components are available:

|
| 23 |
|
| 24 | This release demonstrates a spinning textured cube as an example of the
|
| 25 | vertical slice of XGL functionality running on Ubuntu 14.10 with an Intel
|
| 26 | GPU. Included are instructions for
|
| 27 | [building all the components](https://github.com/KhronosGroup/GL-Next/tree/master/BUILD.md)
|
| 28 | and
|
| 29 | [running the XGL spinning cube demo application](https://github.com/KhronosGroup/GL-Next/tree/master/demos/README.md).
|
| 30 |
|
| 31 | Information on how to enable the API Dump and Validation layers is in
|
| 32 | [layers/README.md](https://github.com/KhronosGroup/GL-Next/tree/master/layers/README.md).
