Pov-Ray Rendering Configure

Configure rendering setting for Pov-Ray.
Pov-Ray version must be equal to or later than 3.7

The dialog is called from menu "Rendering Configure".

Configure PATH

When exporting scene file, Oosawa would write .ini and .pov files on Working directory. And when rendering, Oosawa call Pov-Ray and render them. Please configure these pathes at first.
Note that position of camera for Pov-Ray rendering is set to that of top-left view panel.

When un-existing pathes are set, color buttons at left would be marked red.

Animation is implemented by sequentially exporting (or rendering) snapshot files.

Parameters for rendering

Belows are paremeter settings for Pov-Ray rendering. Please read Pov-Ray help or manual for details.


These parameters determine the quality of radiosity.
Radiosity increase the quality by calculating obscure shadows on convave surfaces.

Note that the radiosity is heavy calculation. Use it only when high quality image is required

Radiocity works even in pretrace mode. Full tracing is more accurate but much heavier. Also, full tracing tends to make unnatural image without large quality parameters.


These patameters determine the quiality of photon mapping.

Calculate the refraction of photons with object refractive index != 1. This enables emulating phenomena like blight spot under a lens.

Note that Photon mapping is also heavy calculation.

Focal Blur

These parameters determine the quality of focal blur.

Object not at focus will be rendered with bokeh. The degree of bokeh is determined by the ratio scale / distance to focus.

The location of focal is determined by the distance from the camera, or numerical coordinates.

Note that focal bulr is also heavy calculation.

Focal blur works well to describe the smallness of the scene. (Bokeh becomes stronger in smaller scale with real camera device).

Note that Focal Blur can be emulated by ensemble rendering.

Output Format

These parameters determines the output image format.

Pov-Ray 3.7 supports hydynamic range image in OpenEXR and HDR. These images has infomation over (255, 255, 255). With several image manupulating softwares, you can add effects like glare afterwards.

Chcking Absolute path, file patn would be witten as absolute path in .ini files. Use if needed when you use some batch-scripting.

Emulating Open GL coloring in Pov-Ray is somewhat time consuming (with large number of coloring parameters). Fast Coloring option omits some coloring parameters and makes rendering more faster (but coloring would be somewhat different tone).
In Pov-Ray line is rendered by sequence of cylinders. If this option is checked, these cylinder would be unicolor being not affected by lighting.
Otherwise, cylinders would be rendered normally (with shading and shadowing).

Render Type

Render type

You can select a region to render by Pov-Ray with this panel. (Working area by default).

Limit of how many times Pov-Ray calculates the light path through transparent surfaces. With smaller number, the rendering becomes faster (with increasing risk of inacculate image). Quality parameter of antialiasing. Smaller threshold and larger depth make better image (with increasing rendering time). Note that if threshold is 0, antialiasing would be turned off. Grid and Locus Filter draws lines for openGL.
In Pov-Ray, there exists no line object and lines are expressed by sequence of cylinders.
This parameter determined the width of cylinders. When you use cylinders to draw bent lines, gaps appear at joints.
If Jointed type is selected, these gaps are filled by spheres.

Lines drawn with open cyliners, not filled by spheres.

This coping method is good when camera approaches to these lines. However, when semi-transparent object is rendered, these spheres would be revealed. Select algorith of space partitioning in Pov-Ray. Sometimes one method is faster than another one considerably. However, which one is faster is on a case by case basis, and you must try rendering to judge which one is better.
