Sprites, defining cut out people

Sprites make the program suitable for adding plants, people and cars to the 3D representation without slowing down the representation but providing a photorealistic view.

For this we need the photo of the objects.

From these photos the definition of sprites can be done very quickly, so you can extend your object library.

Sprites don’t have spatial effect; they are only planes with zero thickness.

They look the same from all viewpoints. The sprite will not rotate with the other 3D solids, but will always face the viewer, so it cannot be seen that it has no depth.

There are several collection of downloadable cut out people i.e https://skalgubbar.se/ or https://www.mrcutout.com/

Definition

For the definition of a sprite you have to do the following steps in the Sprite definition dialog:
• Load a previously saved raster image by Browse button. To make the image selection easier, you have access to skalgubbar.se by clicking Link collection, from where you can download a lot of good quality images. Alternatively, you can select a previously imported raster image on your drawing by Select from drawing.
• Select the 2D symbol of the defined sprite object by Browse button. You can select from the predefined group elements in the design center. By default, you can use the Human-2D symbol.
• Modify the object height if the default value is not convenient.
• Transparency with wireframe. With this option you can make transparent those areas of the image which have the selected background colour. Background colour is defined by a mouse click on the image.
• The program automatically cuts out the areas defined by the background colour and makes those parts transparent in 3D. 
• Click Create button to save your sprite object with its name, category and producer information into the Design Center.

Sprite placement

Once you have completed sprite definition, you can place the new object in the drawing using the Interior menu - Single object command. The rendered photo of the sprite becomes visible if you display the model in the photorealistic view.

Sprite properties
In the Object placement dialog box the parameters of the selected sprite appear: its width and height.
These are static values that only provide information on the main parameters.
If you turn off the Sprite in fixed direction option in the Constrains group, the sprite will not rotate with the other 3D solids, but will always face the viewer, so it cannot be seen that it has no depth.
