Recreating 3D objects is one of the technological advances that perhaps goes unnoticed, but which today generates greater utility among users. That’s why big companies are developing products that allow 3D printing to become something more everyday for people.
The American company Nvidia wants to go further and presented in New Orleans for the Conference on Computer Vision and Pattern Recognition 2022 (CVPR), a research on a method to convert a series of photos into 3D objects using higher calculation. Powerful.
The project called Nvidia 3D MoMa believes that its efficient development could allow architects, designers, concept artists and game developers to quickly import an object into a graphics engine to start working with it, change the scale, change material or experiment with different lighting effects. .

The method uses reverse rendering, a technique widely used to reconstruct a series of photos into a 3D model. In this case, Nvidia is using GPU acceleration and AI to quickly produce 3D objects, David Luebke, vice president of graphics research, said in a blog post on Tuesday, June 21.
To illustrate the explanation, the developers behind this project released a video showing how Nvidia’s MoMa 3D capabilities reconstructed 2D images into 3D representations of each instrument that makes up a jazz band, represented as meshes. .
Luebke added, “By formulating each element of the inverse rendering problem as a GPU-accelerated differentiable component, the NVIDIA 3D MoMa rendering pipeline uses modern AI machines and the raw computing power of NVIDIA GPUs to quickly produce 3D objects that creators can import, modify. and extend without limitation in existing tools”.
The company explains that the reconstruction of the pipeline includes three elements: a 3D mesh model, materials and lighting. The mesh is like a papier-mâché model of a 3D shape constructed from triangles. With it, developers can modify an object to suit their creative vision. Materials are 2D textures superimposed on 3D meshes like a skin. And NVIDIA 3D MoMa’s estimation of how the scene lights up allows creators to modify the lighting of objects later.
