diffusing surfaceの例文

• Although previous workers had pronounced photometric laws 1 and 3, Lambert established the second and added the concept of perfectly diffuse surfaces.
• From that surface the algorithm recursively generates a reflection ray, which is traced through the scene, where it hits another diffuse surface.
• First, a ray is created at an eyepoint and traced through a pixel and into the scene, where it hits a diffuse surface.
• Based on the three laws of photometry and the supposition of perfectly diffuse surfaces, " Photometria " developed and demonstrated the following:
• Caustics are bright patterns caused by the focusing of light off a wide reflective region onto a narrow area of ( near-) diffuse surface.
• For example, if the light source emitted white light and the two diffuse surfaces were blue, then the resulting color of the pixel is blue.
• The color of the pixel now depends on the colors of the first and second diffuse surface and the color of the light emitted from the light source.
• The Oren Nayar reflectance model, developed by Michael Oren and Shree K . Nayar in 1993, predicts reflectance from rough diffuse surfaces for the entire hemisphere of source and sensor directions.
• The earliest optical mice detected movement on pre-printed mousepad surfaces, whereas the modern LED optical mouse works on most opaque diffuse surfaces; it is usually unable to detect movement on specular surfaces like polished stone.
• When this scenario is modeled, the day side displays mobile lid convection with diffuse surface deformation flowing toward the night side, while the night side has a plate tectonic regime of downwelling plates and a deep mantle return flow in the direction of the night side.
• It was created by Cindy M . Goral, Kenneth E . Torrance, Donald P . Greenberg, and Bennett Battaile at the Cornell University Program of Computer Graphics for their paper " Modeling the Interaction of Light Between Diffuse Surfaces " published and presented at SIGGRAPH'84.
