Hi, Recent I have coded the hdr that based on ps_1_1.
In addition, It had quad algorithm. however, when I executed it ,
Screen Quad Object was not rendered. Hmm...
I uploaded src.
shader code:
/* Variable */
float2 HDR_ViewSize;
float HDR_Width = 0.015f ;
float HDR_Power = 0.15f ;
/* Texture */
texture Scene_Frame < string Name = " "; >;
/* Sampler */
sampler2D Sampler_Frame = sampler_state { Texture = <Scene_Frame>; ADDRESSU = CLAMP; ADDRESSV =CLAMP; ADDRESSW=CLAMP; };
/* Structure */
struct Struct_Input
{
float4 Quad_Position : POSITION;
float2 Quad_UV : TEXCOORD;
};
struct Struct_Output
