immediate_vertex

immediate_vertex :: (
    position: Vector3,
    color_scale: Vector4,
    uv: Vector2 = .{},
    normal: Vector3 = .{}
)

Adds one corner to the batch. Every three corners make a triangle, and the batch is drawn when it fills or when something forces a flush.

Parameters

position: Vector3

where the corner is. With the 2D projection z is not used.

color_scale: Vector4

multiplied into the colour the shader finds: the whole colour for set_shader_for_color, the texel for images.

uv: Vector2 = .{}

which point of the texture this corner takes, from 0 to 1.

normal: Vector3 = .{}

the direction the surface faces, for shaders that light it.

set_shader_for_color();

red := Vector4.{1, 0, 0, 1};
immediate_vertex(.{100, 100, 0}, red);
immediate_vertex(.{200, 100, 0}, red);
immediate_vertex(.{150, 200, 0}, red);  // a triangle
