The remaining three camera parameters are the most important, because Will disable rendering of reflective or transmissive objects (they’ll be A value between 4 and 12 is usually good. Reflections, refraction, or in general the maximum recursion depth to The RAYDEPTH parameter tells RAY what the maximum level of Sets the number of additional rays to trace per-pixel to attain higher Supersampling used to obtain higher image quality. The ANTIALIASING parameter controls the maximum level of See what aspect ratio your display has, you can render a simple sphere,Īt a resolution of 512x512 and measure the ratio of its width to its In general, most workstation displays have an aspect ratio of 1.0. The image plane, while keeping the height of the image plane constant. Aspect ratio alters the relative width of By using the aspect ratio parameter, one can produce images which The ASPECTRATIO parameter controls the aspect ratio of the resulting Scaling factor on the height and width of the image plane relative to Relative size of any feature in the frame is twice as big, while theįield of view is decreased slightly. A zoom value of 1.0 is standard, with aĩ0 degree field of view. The ZOOM parameter controls the camera in a way similar to a The PROJECTION keyword must be followed by one of the supportedĬamera projection mode identifiers PERSPECTIVE, PERSPECTIVE_DOF, Written in the sequence they are listed in the examples in this section. Is optional, the remaining camera keywords are required, and must be The first and last keywords required in the definition of a camera are Parameters that control the camera in, PROJECTION, ZOOM,ĪSPECTRATIO, ANTIALIASING, CENTER, RAYDEPTH, May be multiple camera definitions in a scene file, but the last cameraĭefinition overrides all previous definitions. Having a good angle on a scene can make the differenceīetween an average looking scene and a strikingly interesting one. One of the most important parts of any scene, is the camera position and END_SCENE Camera and viewing parameters # An example of a simple scene description skeleton isīEGIN_SCENE RESOLUTION 1024 1024. Output image other than the computer’s available memory and reasonableĮxecution time. There are currently no limits placed on the resolution of an The RESOLUTION keyword isįollowed by an x resolution and a y resolution in terms of pixels onĮach axis. All definitions and declarations of any kind must be inside theīEGIN_SCENE, END_SCENE pair. With the BEGIN_SCENE keyword, and end with the END_SCENE In someĬases, the presence of one keyword will require additional keyword /Īt the moment there are several keywords with values, that must appear Values are either character strings, or floating point numbers. File names and texture names are normally case-sensitive,Īlthough the behavior for file names is operating system-dependent. Keywords can be in caps, lower case, or mixed case for the convenience A scene description fileĬontains keywords, and values associated or grouped with a keyword. Then I may add that feature in the future. Users would rather specify some of these parameters at the command line, Most of the scene parameters in the scene description file itself.
Unlike some other ray tracers out there, RAY requires that you specify (See the API docs for additional info.) Basic Scene Requirements # Most of the objects and their scene description areĬlosely related to the RAY API. The parserĬan’t handle multiple file scene descriptions, although they may beĪdded in the future.
