Set a rendering view Sets the properties needed to define a view in OpenGL. These include field of view, clipping planes, and perspective or orthographic projection modes. In addition a position and orientation can be defined for a virtual camera in 3D space, and the proper view will be generated from these transforms. Cycling '74 Jitter messages to this 3d object TEXT_HERE TEXT_HERE texture output if capture enabled TEXT_HERE dumpout TEXT_HERE Return list of capture target names Return list of capture target names Return ray coords from screen coords Return 6 values representing the world-space endpoints of a ray cast from the screen-x and screen-y arguments. Adapt texture dims to window size Adapt the capture texture dimensions to the context window size (default = 1). Capture to texture flag Capture to texture flag (default = 0) Color mask values Color mask values for red, green, blue, and alpha channels. When set to 0, the corresponding color component is ignored by OpenGL. See glColorMask for more detail. Capture texture dimensions Capture texture dimensions, used when adapt= 0 (default = 256 256). Drawing context Drawing context Background color Background color of viewport and capture texture (default = 0.2 0.2 0.2 1.). Not compatible with non-automatic mode objects. Far clipping plane distance The far clipping plane distance in 3D world (default = 100.) Camera frustum values Camera frustum values (left, right, bottom, top, near, far). projection_mode must be set to frustum for these values to have an effect. The camera's frustum values entirely specify the geometry of the viewing frustum. For more technical documentation on what the six parameters to the frustum attribute mean, see the OpenGL documentation for glFrustum Lens angle The lens angle of the OpenGL camera (default = 45.) Force camera to remain pointed at lookat Force the camera to remain pointed at the lookat value, ignoring orientation messages and attributes (default = 0). Camera view position 3D position at which the camera is pointed (default = 0. 0. 0.) Near clipping plane distance The near clipping plane distance in 3D world (default = 0.1) Orthographic projection mode Orthographic projection mode (default = 0)
0 = orthographic projection off (perspective projection)
1 = orthographic projection on, using lens angle
2 = orthographic projection on, ignoring lens angle TEXT_HERE TEXT_HERE TEXT_HERE TEXT_HERE TEXT_HERE TEXT_HERE Capture texture name Capture texture name Current projection matrix Current projection matrix Camera projection mode Camera projection mode sets how the projection matrix is generated. In standard mode, the camera uses the ortho setting an related attributes such as near, far, lens_angle, etc. to generate the projection matrix. In frustum mode, only the frustum attribute is used to calculate the projection matrix. TEXT_HERE TEXT_HERE TEXT_HERE TEXT_HERE Tripod mode flag Force the camera to orient itself as if mounted on a tripod. Y-axis turn values are applied in world-space regardless of animmode (default = 0). Capture texture type Capture texture type (default = auto) TEXT_HERE TEXT_HERE TEXT_HERE TEXT_HERE TEXT_HERE TEXT_HERE TEXT_HERE TEXT_HERE TEXT_HERE TEXT_HERE TEXT_HERE TEXT_HERE TEXT_HERE TEXT_HERE Current view matrix Current view matrix Viewport coordinates Viewport coordinates which set the left, bottom, width, and height of the viewport (default = 0. 0. 1. 1.) Current view projection matrix Current view projection matrix Viewport coordinate mode Viewport coordinate mode (default = normalized). Determines if the viewport values are absolute or normalized coordinates. TEXT_HERE TEXT_HERE TEXT_HERE TEXT_HERE Multiple jit.gl.camera objects can be added to a single drawing context, and switched between using the enable attribute.
This object requires one argument: the name of a drawing context. A named drawing context is a named instance of a jit.window, jit.pwindow, or jit.matrix object that has an instance of the jit.gl.render object associated with it. Additionally it can reference the name of a jit.gl.node sub-context. This value may also be set via the OB3D drawto attribute. If no argument is present, the object is implicitly added to the first valid drawing context or sub-context found in the current patch or by searching up the patcher hierarchy.
