Visual effects
Prevu3D offers multiple video effects that you can use to beautify your environment.
Easy effects (presets)
Before you get into the more advanced use of effects, you may want to try the effects presets offered by the app, or use them as a baseline to get your own custom effect combination. To do this you can change the preset inside the application settings or you can do it directly by clicking the preset button at the right of the bottom bar of the application and selecting the desired preset.
Advanced effects
Setup
First, you need to access the application settings and click on the "Effects" tab. From there, you'll be able to see and manage the available visual effects applied on the environment.
Available effects
Skybox
The skybox effect is used to show a sky in order to achieved appropriate lighting conditions for any indoor or outdoor environment.
Ambient Occlusion
The ambient occlusion post-processing effect is used to bring some dark areas in surfaces, holes, creases and intersections when they are close each other.
Bloom
The bloom effect is used to dazzle the camera by creating light edges extending from bright boundary areas in an image.
Color Grading
The Color Grading effect is used to correct, modify and improve images colors and luminance that the software creates.
Depth of Field
The Depth of Field effect is used to create a fake bokeh also called background blur to simulate the camera lens focus.
Vignette
The Vignette effect adds a soft dark fade to the edges of the screen.
Double Sided Environment
The double sided environment allows you to enable two sided meshes. Normally a mesh will look transparent when looking from the outside. Two sided environments apply a texture on the outside of the mesh as well.
Sun
The Sun effect can be used in conjunction to the procedural skybox to create a realistic outdoor setting. The sun can be moved horizontally and vertically and should also have shadows and outdoor lighting settings enabled.
- To use the sun you should also use the procedural skybox effect.
- We recommend to align the shadows from the sun with the ones that were originally scanned.
Edge detection
The edge detection effect can be used to highlight the borders of the environment and 3d assets.
