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 | Camera Position, Target Position |
| Resolution | Resolution |
| Pixel Aspect Ratio | Pixel Aspect |
| Focal Length | Focal Length |
| Aperture | Filmback. Film width = Aperture, Film height = Resolution Y / Resolution X * Aperture |
| Near Clipping, Far Clipping | Z-clip range |
| Shutter Time | Shutter speed. Used formula: 1 / (1000 * (1-Shutter Time / FPS)) |
| Focus Distance | Target Position, Target Distance |
| F-Stop | 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.
