It is more expensive (takes longer to render) than a Blinn. Light hits it, but no light bounces off it (see the sphere on the right).Ī blinn (named after Jim Blinn) has some specular highlight, but it isn’t a super sharp highlight so the material looks shiny but not metalic - think of a satin material, flat rubber or matte aluminum.Ī phong is a Maya materials that has a more focused specular highlight (see the sphere on the left). It is a medium gray color.Ī lambert is a shader that has no specular highlights. Maya materials/shaders are fine, but they are limited in what they allow you to do.īefore you do anything, your objects have a Maya shader called a lambert on them. They are a powerful shader that allows for layering, glass, reflection, and more, all with the same material. Here is a bit of information to get you started with Arnold standard materials. We show both quantitatively and qualitatively that our method is highly effective at various tasks such as 3D shape generation, single view reconstruction and shape manipulation, while being significantly faster and more flexible compared to recent 3D generative models.Tutorial - Introduction to Arnold aiStandardSurface Materials
Moreover, the use of standard 2D architectures can help bring more 2D advances into the 3D realm. The generated geometry images are quick to convert to 3D meshes, enabling real-time 3D object synthesis, visualization and interactive editing. Specifically, we propose a novel method to convert 3D shapes into compact 1-channel geometry images and leverage StyleGAN3 and image-to-image translation networks to generate 3D objects in 2D space. This paper addresses a central question: Is it possible to directly leverage 2D image generative models to generate 3D shapes instead? To answer this, we propose XDGAN, an effective and fast method for applying 2D image GAN architectures to the generation of 3D object geometry combined with additional surface attributes, like color textures and normals. However it is difficult to extend this progress into the 3D domain since most current 3D representations rely on custom network components. Generative models for 2D images has recently seen tremendous progress in quality, resolution and speed as a result of the efficiency of 2D convolutional architectures.
