Raytracing tutorial/de

Einführung
Dieses Tutorial soll den Leser in die grundlegende Vorgehensweise des Arbeitsbereichs Raytracing_Render einführen und die meisten der dort vorhandenen Werkzeuge zum Rendern von Bildern kurz vorstellen.



Requirements

 * FreeCAD version 0.16 or above
 * POV-Ray and/or LuxRender is installed on the system
 * In the case of POV-Ray, installation of psicofil's macro is recommended
 * The reader has the basic knowledge to use the Part and PartDesign Workbenches

Modeling
In this example a Cube is used as the study object, but models created in the Part or PartDesign Workbenches can be used instead.


 * 1) Create a new document
 * 2) Activate the Part Workbench
 * 3) Create a Cube. You are free to change its properties in any way.

Now we have a model with which to work with.

Preparing for the render

 * 1) Switch to the Raytracing Workbench
 * 2) Change your View to Perspective. Go to View menu and select Perspective.
 * 3) Set the location for the renderer. Go to the Edit menu and select Preferences. Click on Raytracing and set the location to the executable.
 * 4) Set the size of the rendered image. Go to the Edit menu and select Preferences. Click on Raytracing and set the desired image size.

POV-Ray

 * 1) Select  [[Image:Raytracing_New.png|32px]] New PovRay project. From the dropdown menu pick RadiosityNormal

LuxRender

 * 1) Select [[Image:Raytracing_Lux.png|32px]] New LuxRender project. From the dropdown menu pick LuxClassic

Setting the camera position

 * 1) Position the 3D View to the desired location and distance from the model. In this case we will use the Axonometric View.
 * 2) Select the Project Folder from the Tree View
 * 3) Select [[Image:Raytracing_ResetCamera.png|32px]] Reset camera

Importing the model

 * 1) Select the model to render.
 * 2) Select [[Image:Raytracing_InsertPart.png|32px]] Insert part

Running the Renderer

 * 1) Select  [[Image:Raytracing_Render.png|32px]] Render.
 * 2) Set the path to which the image will be stored.
 * 3) Wait for the rendering to finish. This may take a while.

Viewing the results
FreeCAD will immediately open the image after the render is finished.

We are now finished with the basic workflow for the Raytracing Module.
