Lighting devices and methods for providing daylight to the interior of a structure are disclosed. Some embodiments disclosed herein provide a daylighting device including a tube having a sidewall with a reflective interior surface, a light collecting structure, and a light reflector positioned to ...
contributions of direct and diffuse components of irradiance; these two terms of albedo are sometimes quoted as “black” sky albedo, given by the direct reflectance and depending on the azimuth angle θz, αb(θz), and “white” sky albedo given by the reflectance of diffuse light, αd....
D3DXMATRIX mWorldViewProjection; D3DXVECTOR3 vLightDir[MAX_LIGHTS]; D3DXVECTOR4 vLightDiffuse[MAX_LIGHTS]; D3DXMATRIX mWorld; D3DXMATRIX mView; D3DXMATRIX mProj; // Get the projection and view matrix from the camera class mWorld = g_mCenterMesh * *g_Camera.GetWorldMatrix(); mProj = ...
The meaning of DIRECT LIGHTING is lighting in which the greater part of the light goes directly from the source to the area lit.
Once a soil medium is exposed to a light source, some portion of the light is absorbed, and part is diffusely reflected out of the soil. The final appearance of soil spectra either in the VIS-NIR or MIR is reflection of both the light diffusion and absorption that varies because of the...
如果GI模式设置为“GI_DIFFUSE”,则给出最大漫反射数。 对于大多数场景来说,3-5就足够了。 Ray Epsilon : The distance between the geometry and the light ray when calculating ray intersections for lighting and shadowing. Larger values push rays away from the geometry surface. Lower values are more...

Observation of direct sunlight,diffuse sunlight through cloud and its many variations will develop this understanding.A spotlight or direct flash imitates the type of light we see from direct sunlight,a hard light with strong shadows and extreme contrast.A floodlight/soft box imitates the type of ...
Texture2D gDiffuseMap : register(t0, space0); Texture2D gNormalMap : register(t0, space1); 如果在着色器中没有显式地指定空间寄存器,那么它将自动默认为space0。一般情况下我们通常使用space0,但是对于资源数组来说,使用多重寄存器空间会更加方便,尤其是在数组大小未知的情况下,更是如此。 5.OffsetInDescr...
