Visual effects
Prevu3D offers multiple video effects that you can use to beautify your environment.
Easy effects (presets)
Before diving into the more advanced use of effects, it can be beneficial to experiment with the various rendering style presets that the app offers. To do this, simply click
on the desired preset in the rendering style section of the toolbar. Keep in mind that certain presets may be better suited for indoor or outdoor environments, so don't hesitate to try out different options and see what works best for your project.
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.
