What are textures in 3D Modelling?

3D Texturing is basically wrapping a 2D image around a 3D object and defining how light would affect it. Various software packages have different tools and techniques for adding texture to a 3D model. The texturing stage of the 3D animation pipeline includes unwrapping, texture painting & shading, and rendering.

What is 3D in VFX?

A 3D Texture Artist creates stylized or natural textures and materials that are then applied to 3D models and environments in games, films, or TV shows. They play an important role in the VFX Pipeline. Whether texturing game models or film assets, Texture Artists use a variety of texturing software and techniques.

What’s the purpose of texture painting in Blender?

Texture Painting is a process of making your own textures by using painting tools on the 2D image that is projected onto 3D objects. Usually texture painting is used to create a stylized look, especially looking good on the low-poly models.

How does projective texturing work in Photoshop?

Projective texturing simply put is just projecting a 2D texture onto a 3D scene from a specific view point. It works in a similar fashion to the way we use a camera view point to render a 3D scene onto the 2D back buffer. We first create a viewing frustum from the view point from where we want to project the texture from.

Why do you need to use texture paint?

Usually texture painting is used to create a stylized look, especially looking good on the low-poly models. Texture painting also can be a way of creating details. Meaning that you can literally paint the details onto the object instead of making them out of geometry and wasting polygons on that.

How to calculate the projection coordinates for a texture?

Now we calculate the projection coordinates for sampling the projected texture from. These coordinates are the position the vertex is being viewed from by the location of the projection view point. The coordinates are translated into 2D screen coordinates and moved into the 0.0f to 1.0f range from the -0.5f to +0.5f range.
