CF_Vertex¶
Category: draw
GitHub: cute_draw.h
The full vertex layout CF uses just before sending verts to the GPU.
| Struct Members | Description |
|---|---|
CF_V2 p |
World space position. |
CF_V2 posH |
"Homogenous" position transformed by the camera. |
int n |
For internal use -- For signed-distance functions for rendering shapes. |
CF_V2 shape[8] |
For internal use -- For signed-distance functions for rendering shapes. |
CF_V2 uv |
For internal use -- For sprite rendering. |
CF_Pixel color |
Color for rendering shapes (ignored for sprites). |
float radius |
For internal use -- For applying "chubbiness" factor for shapes, or radii on circle/capsule. |
float stroke |
For internal use -- For shape rendering for border style stroke rendering (no fill). |
float aa |
For internal use -- Factor for the size of antialiasing. |
uint8_t type |
For internal use -- The type of shape to be rendered, used by the signed-distance functions within CF's internal fragment shader. |
uint8_t alpha |
Used for the alpha-component (transparency). |
uint8_t fill |
For internal use -- Whether or not to render shapes as filled or stroked. |
uint8_t unused |
For internal use -- Currently unused but fills needed padding space. |
CF_Color attributes |
Four general purpose floats passed into custom user shaders. |
Remarks¶
You may fill in vertices via callback by cf_set_vertex_callback. See CF_VertexFn.
This is useful when you need to fill in unique attributes per-vertex, or modify any other
bits of the vertex before rendering. This could be used to implement features like dynamically
generated UV's for shape slicing, or complex lighting systems.
