Accessing the Photo Studio Workbench

You can access the Photo Studio Workbench by clicking on Start > Infrastructure > Photo Studio

Photo Studio Optimizer is a set of advanced capabilities which are added to the original capabilities of the Photo Studio workbench.

Using Photo Studio settings, the rendering computation can be automatically distributed on remote workstations through a network. The rendering time is drastically reduced, particularly for huge mock-ups.

User Settings: Photo Studio

Declare the workstations (satellites) here (installation and customization on satellites is required)

The local host will allocate and distribute all the necessary data to the participating satellites, which, in turn, will process the rendering then return the final result back to the local host.

Click on Tools > Options > Infrastructure > Photo Studio > Satellites

What is a 3D Texture?

What is a 3D texture? When using a 2D texture, a picture file is projected on the object using a specific projection method.Using a 3D texture is as sculpting the object directly in the material. The texture is very realistic and gives the illusion of relief. It can be customized through its own parameters (examples : complexity, amplitude, turbulence,)

Which 3D textures can I use? CATIA Photo Studio Optimizer provides 5 different types of 3D textures: Marble Vein Alternate vein Rock Chessboard

Click on the Texture tab

Applying a 3D Texture

Select the 3D texture from the list

Select the material properties

In real time in the 3D viewer, the corresponding texture image is mapped onto the geometry to give a rough visualization of the effect.

The final result is only seen in the rendered image.

What is Bump Mapping?

The bump mapping allows to simulate, using lighting effect, a perturbation of the surface of an object.

This simulation modifies the aspect of the surface of the object. The perturbation is computed based on the contrast of the texture pixels.

For example, bright colors are displayed above dark colors, creating a 3D effect on the object.

What is Global Illumination?

photons

What is global illumination?Global illumination simulates indirect illumination of objects by reflection of light coming from diffuse surfaces.This functionality allows indirect lighting effects among which caustics and color bleeding.

What are photons?Photons are energy particles emitted into the scene by a light source.Once emitted, these energy particles take different paths as they bounce from one object to another.A photon path can evolve in two ways:- photons are either absorbed by an object they hit (through reflection or transmission) and in that case the path ends- photons get lost in space without hitting another object and the path is infinite.Maximum number of reflections and refractions are defined by the user

Setting the Light Parameters for Global Illumination

From the contextual menu of the light, click on Properties

Select Indirect Illumination

Activate photon emission

Set the intensity factor (0 to 100). It corresponds to the light intensity of the photons. It will be combined with the intensity parameter of the Lighting tabIt is recommended to be close to 1

Define the maximum number of photons to be used for the computation of the image (10.000 to 10.000.000).A low value can create puddles
