IVOIRe
Teams DDA, IMAGE
IVOIRe is an image viewer with real-time relighting, allowing you to simulate the look of a texture while moving around the light source.
How does it work ?
The application loads two types of images: The albedo/color of the texture (i.e a normal photograph), and its normal map (you can check the base images with the albedo and normals render modes). It then uses 3D Shaders to recalculate the amount of light at every pixel of the texture using the Blinn-Phong reflection model.
How to use it ?
First, select a texture to view with the drop-down menu at the top of the page. The texture will be loaded in the central area of the page, while the controls become available in the sidebar to the left.
You can move the light source around by clicking and dragging the sphere control in the bottom-left corner. Above the sphere, you can set the lighting parameters of the scene.
To save the viewed texture with the relighting parameters, you can use the Export button.
