Data Fields
sfloat_rgb32	position
	The pixel-coordinates where the origin is located relative to the bottom-left corner of the window.
sfloat_rgba32	clipping_rectangle
	The position in pixels of the clipping rectangle relative to the bottom-left corner of the window, and extent in pixels.
sfloat_rgba32	corner_coordinate
	Double 2D coordinates inside the quad, used to determine the distance from the sides and corner inside the fragment shader.
sfloat_rgba16	fill_color
	background color of the box.
sfloat_rgba16	line_color
	border color of the box.
sfloat_rgba16	corner_shapes
	Shape of each corner, negative values are cut corners, positive values are rounded corners.
float	line_width

Detailed Description

A vertex defining a rectangle on a window. The vertex shader will convert window pixel-coordinates to normalized projection-coordinates.

Field Documentation

clipping_rectangle

sfloat_rgba32 tt::pipeline_box::vertex::clipping_rectangle

The position in pixels of the clipping rectangle relative to the bottom-left corner of the window, and extent in pixels.

corner_coordinate

sfloat_rgba32 tt::pipeline_box::vertex::corner_coordinate

Double 2D coordinates inside the quad, used to determine the distance from the sides and corner inside the fragment shader.

x = Number of pixels to the right from the left edge of the quad. y = Number of pixels above the bottom edge. z = Number of pixels to the left from the right edge of the quad. w = Number of pixels below the top edge.

The rasteriser will interpolate these numbers, so that inside the fragment shader the distance from a corner can be determined easily.

corner_shapes

sfloat_rgba16 tt::pipeline_box::vertex::corner_shapes

Shape of each corner, negative values are cut corners, positive values are rounded corners.

fill_color

sfloat_rgba16 tt::pipeline_box::vertex::fill_color

background color of the box.

line_color

sfloat_rgba16 tt::pipeline_box::vertex::line_color

border color of the box.

position

sfloat_rgb32 tt::pipeline_box::vertex::position

The pixel-coordinates where the origin is located relative to the bottom-left corner of the window.
