Maxwell Camera is an object network which extends the native Houdini camera parameters with Maxwell Render specific options. The node is linked with a normal Houdini camera node and displays only the main parameters which are understood by Maxwell Render.
The following table summarizes the parameters which are translated to the Maxwell scene.
Houdini camera node | Maxwell Render camera |
Translate, Rotate, Pivot, Look At, Look At Up Vector, Path Object, Roll | |
Resolution | |
Pixel Aspect Ratio | |
Focal Length | |
Aperture | Filmback. Film width = Aperture, Film height = Resolution Y / Resolution X * Aperture |
Near Clipping, Far Clipping | |
Shutter Time | Shutter speed. Used formula: 1 / (1000 * (1-Shutter Time / FPS)) |
Focus Distance | |
F-Stop |
All the native camera parameters can be edited with opening the network node (Enter key or double click).
The specific parameters are located on a new tab called Maxwell.
- Shutter: specifies shutter speed value of the Maxwell camera.
- ISO: specifies the film's light- sensitivity; higher ISO is more sensitive.
- Aperture: controls the shape of the “bokeh” effect caused by bright spots in the parts of the render that are out of focus. (Circular or Polygonal)
- Blades: specifies the number of blades for Polygonal diaphragm.
- Angle: specifies rotation angle of aperture opening for Polygonal diaphragm.
- Shift Offset: specifies the offset of the lens position horizontally and vertically which can be useful to correct geometric perspective distortion.
