Hi, I was playing with light source parameters in the Chicago sample and found that there is some shadow artifacts when using values higher than 90 for the FOV parameter. Just wanted to know that is there a specified range for the FOV parameter or it isn't possible to have light sources with FOV set to 360 at all?
test system : Windows 7 + ATI RadeonHD 4890 + 10.6 drivers + Horde3D Beta4 r251
Code:
// Add light source
H3DNode light = h3dAddLightNode( H3DRootNode, "Light1", lightMatRes, "LIGHTING", "SHADOWMAP" );
h3dSetNodeTransform( light, 0, 10, 0, -30, 0, 0, 1, 1, 1 );
h3dSetNodeParamF( light, H3DLight::RadiusF, 0, 50 );
h3dSetNodeParamF( light, H3DLight::FovF, 0, 270 );
h3dSetNodeParamI( light, H3DLight::ShadowMapCountI, 4 );
h3dSetNodeParamF( light, H3DLight::ShadowSplitLambdaF, 0, 0.9f );
h3dSetNodeParamF( light, H3DLight::ShadowMapBiasF, 0, 0.001f );
h3dSetNodeParamF( light, H3DLight::ColorF3, 0, 0.8f );
h3dSetNodeParamF( light, H3DLight::ColorF3, 1, 0.2f );
h3dSetNodeParamF( light, H3DLight::ColorF3, 2, 0.2f );
H3DNode light = h3dAddLightNode( H3DRootNode, "Light1", lightMatRes, "LIGHTING", "SHADOWMAP" );
h3dSetNodeTransform( light, 0, 10, 0, -30, 0, 0, 1, 1, 1 );
h3dSetNodeParamF( light, H3DLight::RadiusF, 0, 50 );
h3dSetNodeParamF( light, H3DLight::FovF, 0, 270 );
h3dSetNodeParamI( light, H3DLight::ShadowMapCountI, 4 );
h3dSetNodeParamF( light, H3DLight::ShadowSplitLambdaF, 0, 0.9f );
h3dSetNodeParamF( light, H3DLight::ShadowMapBiasF, 0, 0.001f );
h3dSetNodeParamF( light, H3DLight::ColorF3, 0, 0.8f );
h3dSetNodeParamF( light, H3DLight::ColorF3, 1, 0.2f );
h3dSetNodeParamF( light, H3DLight::ColorF3, 2, 0.2f );
