Data Fields
sfloat_rgba32	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.
float	alpha
	The alpha value of the resulting pixels inside the quad.
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_rgba32	corner_radii
	Shape of each corner, negative values are cut corners, positive values are rounded corners.
sfloat_rgba16	fill_color
	background color of the box.
sfloat_rgba16	line_color
	border color of the box.
float	line_width
sfloat_rgba32	atlas_position
	The x, y coordinate inside the texture-atlas, z is used as an index in the texture-atlas array.
sfloat_rgb32	position
	The pixel-coordinates where the origin is located relative to the bottom-left corner of the window.
sfloat_rgba32	clippingRectangle
	Clipping rectangle. (x,y)=bottom-left, (z,w)=top-right.
sfloat_rgb32	textureCoord
	The x, y (relative to bottom-left) coordinate inside the texture-atlas, z is used as an index in the texture-atlas array.
sfloat_rgba16	color
	The color of the glyph.

Detailed Description

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

Field Documentation

alpha

float v1::vertex::alpha

The alpha value of the resulting pixels inside the quad.

atlas_position

sfloat_rgba32 v1::vertex::atlas_position

The x, y coordinate inside the texture-atlas, z is used as an index in the texture-atlas array.

clipping_rectangle

sfloat_rgba32 v1::vertex::clipping_rectangle

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

clippingRectangle

sfloat_rgba32 v1::vertex::clippingRectangle

Clipping rectangle. (x,y)=bottom-left, (z,w)=top-right.

color

sfloat_rgba16 v1::vertex::color

The color of the glyph.

corner_coordinate

sfloat_rgba32 v1::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_radii

sfloat_rgba32 v1::vertex::corner_radii

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

fill_color

sfloat_rgba16 v1::vertex::fill_color

background color of the box.

line_color

sfloat_rgba16 v1::vertex::line_color

border color of the box.

position [1/2]

sfloat_rgba32 v1::vertex::position

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

position [2/2]

sfloat_rgb32 v1::vertex::position

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

textureCoord

sfloat_rgb32 v1::vertex::textureCoord

The x, y (relative to bottom-left) coordinate inside the texture-atlas, z is used as an index in the texture-atlas array.
