Using Rendering Options

The Rendering options you can find in Photo Studio enables you to create realistic pictures you may need at the beginning of your design projects.

According to the license you have with your CATIA, you will have access to the simple Photo Studio workbench or to the more exhaustive one.

This task shows you how:

Use the Rendering Options: Simple Workbench

You can use the rendering options through a simple workbench.

  1. Select Rendering Options in the Render toolbar.

    The Rendering Options dialog box opens:

  2. Select the Quality.

    Note:

    Three choices are available: Low, Medium or High quality. You can define the quality of the rendering (anti-aliasing, reflections, refractions). The better the quality is, the longer the Rendering time will be. By using anti-aliasing, a technique that is based on shading the pixels along the borders of the lines, using different tonalities of the same color to average the geometry:



    However, anti-aliasing is huge resource consumer: rendering time can be doubled. In some cases, it might not be necessary to use the maximum level of anti-aliasing.

    Realistic Lighting: when activated, provides realistic soft shadowing. Surfaces not fully exposed are attenuated so that they do not receive the full contribution of the ambient lighting. When this option is activated, computing time is longer.

    Resolution:

  3. Select the Resolution.

    Note:

    • Window: uses the same resolution as the 3D window (one pixel in the 3D gives one rendered pixel).

    • DPI: applies a user-defined ratio (one pixel in the 3D gives more than one rendered pixel). The ratio is given in pixels per unit length. This allows to have images larger than the screen resolution.

      Tip: When selected, you can select its value by using the Up and Down arrows.

  4. Set these options according to your needs.

  5. Click OK to validate your settings and quit the Rendering Options dialog box.

Use the Rendering Options: Exhaustive Workbench

You can use the rendering options through an exhaustive workbench.

  1. Click Rendering Options in the Render toolbar.

    By default the Rendering Options dialog box opens:

  2. Select predefined settings from the lists.


    • Lens: Pinhole, 15mm, 20mm, 24mm, 28mm, 35mm, 50mm, 85mm, 135mm, 200mm or Custom.
    • Exposure: Classic Lights, Sunny, Cloudy, Indoor, Moonlight, Custom.
    • Lighting: Simple, Realistic, Caustics, Dispersion, Custom.
    • Quality: Low, Medium, High, Very High, Custom.
    • Resolution: Window, Window DPI, TV (640x480), HDTV (1920x1080), A4, A3, Letter Legal, 10x15cm/4x6in, 13x19cm/5x7.5 in, 15x23/8x12 in, 30x46cm/12x18in, Custom.
    Tip: The lists you can find by default proposes predefined options you do not need to parameter.

  3. See About Rendering Options to define the settings according to your specific needs if the predefined ones do not meet the result expected.

    Tip: When selecting the Custom options from the lists the content of the dialog box becomes dynamic, other options appear to let you About Rendering Options as you wish.

  4. Click OK when satisfied.
