realistic image from the 3D viewer display.,第15页,15,Copyright DASSAULT SYSTEMES 2002,Computation parameters:,Default parameters have been predefined to help the user to get quickly a realistic image.,If an active environment has been defined by the user,it will be taken into account by the Quick Render.,If active lights exist in the session,they will be taken into account.If no light is active,a default light positioned at the current view point will be used.,The image destination file can be defined in the settings.,A precise size in pixels can be defined for the image in the settings.,Applying material:,If a material is applied to a part being instanced in the product,all the instances will have the same attributes.Ex:the buttons,You can also apply the material to the instance itself so that the same part has different effects in the image,depending on its instance.,Additional Information.,第16页,16,Copyright DASSAULT SYSTEMES 2002,Environment Management,In this

parameters,Additional information,第30页,30,Copyright DASSAULT SYSTEMES 2002,What about light sources?,Light sources are not just used to light up the environment and make object visible.By generating shadows and illumination variations on the object surface,they give the image its effect of relief and make it more realistic.,Which light sources can I use in Photo Studio?,“Ponctual”light sources:,A,Spot light,:,It projects a cone of light from a given point to a given direction.It is the only type of light source which concentrates lights rays on a specific part of the scene.It is thus very useful to highlight details.,A,Point light,:,It scatters light in all directions from a given point like an electric lamp.,A,Directional light,:,The light reaches the scene in the form of parallel rays as if it had been emitted by a plane.It simulates light emitted by a very distant source such as the sun.,Surfacic light sources,creating more realistic images by generating soft
