◆ SetBlendEquation()

void RSX_FUNC() SetBlendEquation	(	gcmContextData *	context,
		u16	color,
		u16	alpha
	)

Set the blend equation.

The blend equations determine how a new pixel (the “source” color) is combined with a pixel already in the framebuffer (the “destination” color). This function specifies one blend equation for the RGB-color components and one blend equation for the alpha component.

These equations use the source and destination blend factors specified by rsxSetBlendFunc. See rsxSetBlendFunc for a description of the various blend factors.

In the equations that follow, source and destination color components are referred to as R_s, G_s, B_s, A_s and R_d, G_d, B_d, A_d, respectively. The result color is referred to as R_r, G_r, B_r, A_r. The source and destination blend factors are denoted s_R, s_G, s_B, s_A and d_R, d_G, d_B, d_A, respectively. For these equations all color components are understood to have values in the range [0,1].

Mode	R_r	G_r	B_r	A_r
GCM_FUNC_ADD	R_ss_R+R_dd_R	G_ss_G+G_dd_G	B_ss_B+B_dd_B	A_ss_A+A_dd_A
GCM_MIN	min(R_s,R_d)	min(G_s,G_d)	min(B_s,B_d)	min(A_s,A_d)
GCM_MAX	max(R_s,R_d)	max(G_s,G_d)	max(B_s,B_d)	max(A_s,A_d)
GCM_FUNC_SUBTRACT	R_ss_R-R_dd_R	G_ss_G-G_dd_G	B_ss_B-B_dd_B	A_ss_A-A_dd_A
GCM_FUNC_REVERSE_SUBTRACT	R_dd_R-R_ss_R	G_dd_G-G_ss_G	B_dd_B-B_ss_B	A_dd_A-A_ss_A

The results of these equations are clamped to the range [0,1].

The GCM_MIN and GCM_MAX equations are useful for applications that analyze image data (image thresholding against a constant color, for example). The GCM_FUNC_ADD equation is useful for antialiasing and transparency, among other things.

Initially, both the RGB blend equation and the alpha blend equation are set to GCM_FUNC_ADD.

Notes

The GCM_MIN, and GCM_MAX equations do not use the source or destination factors, only the source and destination colors.

Parameters

context	Pointer to the context object
color	Specifies the RGB blend equation, how the red, green, and blue components of the source and destination colors are combined.
alpha	Specifies the alpha blend equation, how the alpha component of the source and destination colors are combined.

◆ SetBlendFunc()

void RSX_FUNC() SetBlendFunc	(	gcmContextData *	context,
		u16	sfcolor,
		u16	dfcolor,
		u16	sfalpha,
		u16	dfalpha
	)

Specify pixel arithmetic.

In RGBA mode, pixels can be drawn using a function that blends the incoming (source) RGBA values with the RGBA values that are already in the frame buffer (the destination values). Blending is initially disabled. Use rsxSetBlendEnable to enable and disable blending.

rsxSetBlendFunc defines the operation of blending when it is enabled. sfcolor and and sfalpha specify which method is used to scale the source color and alpha components. dfcolor and and dfalpha specify which method is used to scale the destination color and alpha components. The possible methods are described in the following table. Each method defines four scale factors, one each for red, green, blue, and alpha. In the table and in subsequent equations, source and destination color components are referred to as R_s, G_s, B_s, A_s and R_d, G_d, B_d, A_d, respectively. The color specified by rsxSetBlendColor is referred to as R_c, G_c, B_c, A_c. They are understood to have integer values between 0 and k_R, k_G, k_B, k_A, where

k_c = 2^m_c - 1

and m_R, m_G, m_B, m_A is the number of red, green, blue, and alpha bitplanes.

Source and destination scale factors are referred to as s_R, s_G, s_B, s_A and d_R, d_G, d_B, d_A. The scale factors described in the table, denoted f_R, f_G, f_B, f_A, represent either source or destination factors. All scale factors have range [0,1].

GCM_ONE_MINUS_CONSTANT_ALPHA	1-A_c	1-A_c	1-A_c	1-A_c
GCM_SRC_ALPHA_SATURATE	i	i	i	1

In the table,

i = min(A_s/k_A, 1 - A_d/k_A)

To determine the blended RGBA values of a pixel when drawing in RGBA mode, the equation defined by rsxSetBlendEquation us used. In the default mode (GCM_FUNC_ADD for RGB and alpha equations), the equations are the following:

R_d = min(k_R, R_ss_R + R_dd_R)
G_d = min(k_G, G_ss_G + G_dd_G)
B_d = min(k_B, B_ss_B + B_dd_B)
A_d = min(k_A, A_ss_A + A_dd_A)

Despite the apparent precision of the above equations, blending arithmetic is not exactly specified, because blending operates with imprecise integer color values. However, a blend factor that should be equal to 1 is guaranteed not to modify its multiplicand, and a blend factor equal to 0 reduces its multiplicand to 0. For example, when sfcolor is GCM_SRC_ALPHA, fdcolor is GCM_ONE_MINUS_SRC_ALPHA, and A_s is equal to k_A, the equations reduce to simple replacement:

R_d = R_s ; G_d = G_s ; B_d = B_s

Examples

Transparency is best implemented using blend function (sfcolor = sfalpha = GCM_SRC_ALPHA, dfcolor = dfalpha = GCM_ONE_MINUS_SRC_ALPHA) with primitives sorted from farthest to nearest. Note that this transparency calculation does not require the presence of alpha bitplanes in the frame buffer.

Blend function (GCM_SRC_ALPHA, GCM_ONE_MINUS_SRC_ALPHA) is also useful for rendering antialiased points and lines in arbitrary order.

Polygon antialiasing is optimized using blend function (GCM_SRC_ALPHA_SATURATE, GCM_ONE) with polygons sorted from nearest to farthest.

Destination alpha bitplanes, which must be present for this blend function to operate correctly, store the accumulated coverage.

Notes

Incoming (source) alpha is correctly thought of as a material opacity, ranging from 1.0 ( k_A ), representing complete opacity, to 0.0 (0), representing complete transparency.
