| 10 | Introduction |
| 11 | ------------ |
| 12 | |
| 13 | Mesa uses an even/odd version number scheme like the Linux kernel. |
| 14 | Odd numbered versions (such as 5.1) designate new developmental releases. |
| 15 | Even numbered versions (such as 6.0) designate stable releases. |
| 16 | |
| 17 | Mesa version 6.0 signifies two things: |
| 18 | |
| 19 | 1. A stabilization of the 5.1 development release |
| Brian Paul | d7af11a | 2004-01-07 14:51:30 +0000 | [diff] [blame] | 20 | 2. Implementation of the OpenGL 1.5 specification. When you query |
| 21 | glGetString(GL_VERSION) "1.5" will be returned (as long as the |
| 22 | driver supports all the required features). |

| 24 | |
| 25 | Note that the Mesa major version number is incremented with the OpenGL |
| 26 | minor version number: |
| 27 | |
| 28 | Mesa 1.x == OpenGL 1.0 |
| 29 | Mesa 2.x == OpenGL 1.1 |
| 30 | Mesa 3.x == OpenGL 1.2 |
| 31 | Mesa 4.x == OpenGL 1.3 |
| 32 | Mesa 5.x == OpenGL 1.4 |
| 33 | Mesa 6.x == OpenGL 1.5 |
| 34 | |
| 35 | |
| 36 | |
| 37 | New Features |
| 38 | ------------ |
| 39 | |
| 40 | Mesa 5.1 already had all the new features of OpenGL 1.5, implemented as |
| 41 | extensions. These extensions were simply promoted to standard features: |
| 42 | |
| 43 | GL_ARB_occlusion_query extension |
| 44 | GL_ARB_texture_non_power_of_two extension |
| 45 | GL_ARB_vertex_buffer_object extension |

| 50 | Device Drivers |
| 51 | -------------- |
| 52 | |
| 53 | Mesa advertises itself as either OpenGL 1.2 or OpenGL 1.3 depending on |
| 54 | the device driver. For example, if the driver enables all the ARB |
| 55 | extensions which are part of OpenGL 1.3 then glGetString(GL_VERSION) |
| 56 | will return "1.3". Otherwise, it'll return "1.2". |
| 57 | |
| 58 | A number of Mesa's software drivers haven't been actively maintained for |
| 59 | some time. We rely on volunteers to maintain many of the drivers. |
| 60 | Here's the current status of all included drivers: |
| 61 | |
| 62 | |
| 63 | Driver Status |
| 64 | ---------------------- --------------------- |
| 65 | XMesa (Xlib) implements OpenGL 1.5 |
| 66 | OSMesa (off-screen) implements OpenGL 1.5 |
| 67 | FX (3dfx Voodoo1/2) implements OpenGL 1.3 |
| 68 | SVGA implements OpenGL 1.3 |
| 69 | Wind River UGL implements OpenGL 1.3 |
| 70 | Windows/Win32 implements OpenGL 1.5 |
| 71 | DJGPP implements OpenGL 1.5 |
| 72 | GGI implements OpenGL 1.3 |
| 73 | BeOS implements OpenGL 1.5 |
| 74 | Allegro needs updating |
| 75 | D3D needs updating |
