C# 클래스 Axiom.Graphics.ShadowVolumeExtrudeProgram

Static class containing source for vertex programs for extruding shadow volumes.
This exists so we don't have to be dependent on an external media files. is used so we don't have to rely on particular plugins. assembler contents of this file were generated from the following Cg: // Point light shadow volume extrude void shadowVolumeExtrudePointLight_vp ( float4 position : POSITION, float wcoord : TEXCOORD0, out float4 oPosition : POSITION, uniform float4x4 worldViewProjMatrix, uniform float4 lightPos // homogenous, object space ) { // extrusion in object space // vertex unmodified if w==1, extruded if w==0 float4 newpos = (wcoord.xxxx * lightPos) + float4(position.xyz - lightPos.xyz, 0); oPosition = mul(worldViewProjMatrix, newpos); } // Directional light extrude void shadowVolumeExtrudeDirLight_vp ( float4 position : POSITION, float wcoord : TEXCOORD0, out float4 oPosition : POSITION, uniform float4x4 worldViewProjMatrix, uniform float4 lightPos // homogenous, object space ) { // extrusion in object space // vertex unmodified if w==1, extruded if w==0 float4 newpos = (wcoord.xxxx * (position + lightPos)) - lightPos; oPosition = mul(worldViewProjMatrix, newpos); } // Point light shadow volume extrude - FINITE void shadowVolumeExtrudePointLightFinite_vp ( float4 position : POSITION, float wcoord : TEXCOORD0, out float4 oPosition : POSITION, uniform float4x4 worldViewProjMatrix, uniform float4 lightPos, // homogenous, object space uniform float extrusionDistance // how far to extrude ) { // extrusion in object space // vertex unmodified if w==1, extruded if w==0 float3 extrusionDir = position.xyz - lightPos.xyz; extrusionDir = normalize(extrusionDir); float4 newpos = float4(position.xyz + ((1 - wcoord.x) * extrusionDistance * extrusionDir), 1); oPosition = mul(worldViewProjMatrix, newpos); } // Directional light extrude - FINITE void shadowVolumeExtrudeDirLightFinite_vp ( float4 position : POSITION, float wcoord : TEXCOORD0, out float4 oPosition : POSITION, uniform float4x4 worldViewProjMatrix, uniform float4 lightPos, // homogenous, object space uniform float extrusionDistance // how far to extrude ) { // extrusion in object space // vertex unmodified if w==1, extruded if w==0 // -ve lightPos is direction float4 newpos = float4(position.xyz - (wcoord.x * extrusionDistance * lightPos.xyz), 1); oPosition = mul(worldViewProjMatrix, newpos); }
