Note These calls rely on the following inline shortcut function: Setting the matrix to the identity causes the system to use the delta values in the bump map unmodified, but this is not a requirement.

#Blender apply bump map code#

When the blending operations and arguments are set, the following code example sets the 2x2 bump mapping matrix to the identity matrix by setting the D3DTSS_BUMPENVMAPMAT00 and the D3DTSS_BUMPENVMAPMAT11 members of D3DTEXTURESTAGESTATETYPE to 1.0. Stage 1: The bump map - Use luminance for this example.Д3dDevice->SetTextureStageState( 1, D3DTSS_TEXCOORDINDEX, 1 ) Д3dDevice->SetTextureStageState( 1, D3DTSS_COLOROP, D3DTOP_BUMPENVMAPLUMINANCE) Д3dDevice->SetTextureStageState( 1, D3DTSS_COLORARG1, D3DTA_TEXTURE ) Д3dDevice->SetTextureStageState( 1, D3DTSS_COLORARG2, D3DTA_CURRENT ) Д3dDevice->SetTextureStageState( 2, D3DTSS_TEXCOORDINDEX, 0 ) Д3dDevice->SetTextureStageState( 2, D3DTSS_COLOROP, D3DTOP_ADD ) Д3dDevice->SetTextureStageState( 2, D3DTSS_COLORARG1, D3DTA_TEXTURE ) Д3dDevice->SetTextureStageState( 2, D3DTSS_COLORARG2, D3DTA_CURRENT ) Set the color operations and arguments to prepare forД3dDevice->SetTextureStageState( 0, D3DTSS_COLOROP, D3DTOP_MODULATE ) Д3dDevice->SetTextureStageState( 0, D3DTSS_COLORARG1, D3DTA_TEXTURE ) Д3dDevice->SetTextureStageState( 0, D3DTSS_COLORARG2, D3DTA_DIFFUSE ) Д3dDevice->SetTextureStageState( 0, D3DTSS_ALPHAOP, D3DTOP_SELECTARG1 ) Д3dDevice->SetTextureStageState( 0, D3DTSS_ALPHAARG1, D3DTA_TEXTURE ) Д3dDevice->SetTextureStageState( 0, D3DTSS_TEXCOORDINDEX, 1 ) If( d3dCaps.MaxTextureBlendStages SetTexture( 0, d3dBaseTexture ) ДЄfter setting the textures to their blending stages, the following code example prepares the blending operations and arguments for each stage. Does this device support up to three blending stages? If ( 0 = d3dCaps.TextureOpCaps & ( D3DTEXOPCAPS_BUMPENVMAP | Does this device support the two bump mapping blend operations? The following code example checks device capabilities to detect support for bump mapping in the current device, using the given criteria. Use IDirect3D9::CheckDeviceFormat with D3DUSAGE_QUERY_LEGACYBUMPMAP to see if a format is supported for bump mapping.ДЄdditionally, applications should check the device capabilities to make sure the device supports an appropriate number of blending stages, usually at least three, and exposes at least one bump-mapping pixel format. In this article Detecting Support for Bump MappingДЄ device can perform bump mapping if it supports either the D3DTOP_BUMPENVMAP or D3DTOP_BUMPENVMAPLUMINANCE texture blending operation.
