| Dependencies |
| |
| OpenGL 1.1 is required |
| The extension is written against the OpenGL 1.3 Specification. |
| |
| Overview |
| |
| |
| This extension defines a new mesh primitive. |
| The primitive can only be used with vertex arrays and cannot be used in |
| immediate mode. The application must arrange the vertices in row major format. |
| For example if a quad mesh is 4 vertices wide the, vertices in the first |
| row are the first 4 vertices and vertices in the second row are vertices 5 |
| through 8. |

| Issues |
| |
| 1. Should glDrawMultiMeshArraysSUN and/or glDrawRangeMeshArraysSUN |
| be included? |
| |
| No. small meshes are not that common. A mesh is like a series of |
| triangle or quad meshes already. |
| |
| |
| New Procedures and Functions |
| |
| glDrawMeshArraysSUN( GLenum mode, GLint first, GLsizei count, GLsizei width ) |
| |
| New Tokens |
| |
| Accepted by the <mode> parameter of DrawMeshArraysSun, |
| |
| QUAD_MESH_SUN 0x8614 |
| TRIANGLE_MESH_SUN 0x8615 |
| |
| Additions to Chapter 2 of the 1.3 GL Specification (OpenGL Operation) |
| |
| Section 2.8 Vertex Arrays: |
| |
| The command |
| |
| void DrawMeshArraysSUN( enum mode, int first, sizei count, sizei width ); |
| |
| constructs a mesh primitive using the elements first through first+count-1 |
| of each enabled array. The mode specifies if it is a quad mesh or triangle |
| mesh. The only token values accepted by mode are QUAD_MESH_SUN and |
| TRIANGLE_MESH_SUN. Width specifies how many vertices are in each row |
| of the mesh. The elements must be arranged in row major order within the |
| arrays. |

| Errors |
| |
| INVALID_VALUE is generated if <count> is not an even multiple of |
| width. |
| |
| INVALID_ENUM is generated if <mode> is not QUAD_MESH_SUN or |
| TRIANGLE_MESH_SUN. |
