| handleDynamicTopology | True if topological changes should be handled | 1 |
| fixMergedUVSeams | True if UV seams should be handled even when duplicate UVs are merged | 1 |
| keepLines | keep and draw lines (false by default) | 0 |
| vertPosIdx | If vertices have multiple normals/texcoords stores vertices position indices | |

| lineSmooth | Enable smooth line rendering | 0 |
| pointSmooth | Enable smooth point rendering | 0 |
| primitiveType | Select types of primitives to send (necessary for some shader types such as geometry or tesselation) | |
| blendEquation | if alpha blending is enabled this specifies how source and destination colors are combined | |
| sfactor | if alpha blending is enabled this specifies how the red, green, blue, and alpha source blending factors are computed | |
| dfactor | if alpha blending is enabled this specifies how the red, green, blue, and alpha destination blending factors are computed | |
