Blending:Function:Source Property

Short Name: Blending.Function.Source

Installed With: Full Development System

Class: SceneObject Properties

Reads or writes the blend factor you apply to the color values of the incoming fragment.

The following source and destination color components are described as (R_s, G_s, B_s, A_s) for source components and (R_d, G_d, B_d, A_d) for destination components.

The components have integer values between 0 and (k_R, k_G, k_B, k_A), where k_R=2^mR 1, k_G=2^mG 1, k_B=2^mB 1, and k_A=2^mA 1.

(m_R, m_G, m_B, m_A) is the number of bitplanes for each red, green, blue, and alpha value.

Values

0	Zero— (default) (0, 0, 0, 0)
1	One—(1, 1, 1, 1)
2	Destination Color—(Rd/kR, Gd/kG, Bd/kB, Ad/kA)
3	One Minus Destination Color—(1, 1, 1, 1)−(Rd/kR, Gd/kG, Bd/kB, Ad/kA)
4	Source Alpha—(As/kA, As/kA, As/kA, As/kA)
5	One Minus Source Alpha—(1, 1, 1, 1)−(As/kA, As/kA, As/kA, As/kA)
6	Destination Alpha—(Ad/kA, Ad/kA, Ad/kA, Ad/kA)
7	One Minus Destination Alpha—(1, 1, 1, 1)−(Ad/kA, Ad/kA, Ad/kA, Ad/kA)
8	Source Alpha Saturate—(i, i, i, 1) where i=min (As, kA, Ad)/kA
