Module vbo
A friendly wrapper for setting up vertex buffer objects
| vbo:bind () |
Bind the VBO
This will upload data to the GPU if the vbo.dirty flag is marked |
| vbo:unbind () |
Unbind the VBO |
| vbo:enable_position_attribute (shader, name) |
Set the buffer's position data as the source of a shader's attribute |
| vbo:disable_position_attribute (shader, name) |
Disable the binding of position data as the source of a shader's attribute |
| vbo:enable_normal_attribute (shader, name) |
Set the buffer's normal data as the source of a shader's attribute |
| vbo:disable_normal_attribute (shader, name) |
Disable the binding of normal data as the source of a shader's attribute |
| vbo:enable_color_attribute (shader, name) |
Set the buffer's color data as the source of a shader's attribute |
| vbo:disable_color_attribute (shader, name) |
Disable the binding of color data as the source of a shader's attribute |
| vbo:enable_texcoord_attribute (shader, name) |
Set the buffer's texcoord data as the source of a shader's attribute |
| vbo:disable_texcoord_attribute (shader, name) |
Disable the binding of texcoord data as the source of a shader's attribute |
| vbo:draw (primitive, first, count) |
Submit the buffer to be rendered |
