d3d_model_primitive_begin(ind, kind)
| Argument | Description |
|---|---|
| ind | The index of the model to add the primitive to. |
| kind | The kind of primitive you are going to draw. |
Returns: N/A
This function must be called before you can define any primitives for a model. There are 6 types of primitives you can define with the following constants:
- pr_pointlist
- pr_linelist
- pr_linestrip
- pr_trianglelist
- pr_trianglestrip
- pr_trianglefan - (This is not available on the HTML5 target platform and may not work correctly on some devices for other platforms)
The following image illustrates basically how these should look
and also the order in which you should define the vertexes:
model[2] = d3d_model_create();
d3d_model_primitive_begin(model[2], pr_trianglestrip);
d3d_model_vertex(model[2], 100, 100, 0);
d3d_model_vertex(model[2], 100, 200, 0);
d3d_model_vertex(model[2], 150, 150, 200);
d3d_model_vertex(model[2], 100, 200, 0);
d3d_model_vertex(model[2], 200, 200, 0);
d3d_model_vertex(model[2], 150, 150, 200);
d3d_model_vertex(model[2], 200, 200, 0);
d3d_model_vertex(model[2], 100, 100, 0);
d3d_model_vertex(model[2], 150, 150, 200);
d3d_model_vertex(model[2], 100, 100, 0);
d3d_model_vertex(model[2], 100, 200, 0);
d3d_model_vertex(model[2], 200, 200, 0);
d3d_model_primitive_end(model[2]);
The above code will define a tetrahedron and add it to the model.
