What Is 3D Texturing?

 

Texture Creation- Basic Techniques

There are the following main methods of creating textures:

• rendering in a graphic 2d editor, for example, Photoshop;
• creating a texture in a 3D painting package such as Mudbox, ZBrush, Mari or 3D-Coat;
• construction based on procedural maps;
• Complex application of procedural techniques of various kinds, 2d and 3d format.

For example, if you need to create a brick wall texture, then you need to perform the following sequence of actions:

• Creation of a plane, search and refinement of the texture of a brick wall. Creation of a seamless texture of a brick wall in 2D programs;
• a gloss map is created to give the texture of the brick wall a light, realistic sheen;
• surface roughness is obtained by creating a roughness map;
• the reflectivity of a brick wall is created using a reflection map.

After going through the sequence of these stages, the modeled plane will turn into a realistic natural brick wall.

Types of Texturing

There are the following main types of texturing

• relief texturing;
• MIP texturing.

Relief texturing is a technology for working with 3D polly graphics that allows you to create the surface of a modeled object in a rich and realistic design.

Types of bump mapping

• Bump mapping is a technology that allows you to give the surface of a modeled object a relief effect and thoroughly detail it. This effect is created by virtually displacing pixels using a single band heightmap and a light source. As a result, participants with varying degrees of illumination can be obtained. Bump mapping is used to create difficult bumpy surfaces, protrusions and depressions.
• Normal mapping – a method for changing the normal of a pixel based on a color normal map. In this case, the changes are saved in texels. This method is the most accurate due to the use of 3 texture channels in the normal map.
• Parallax occlusion mapping is a local ray tracing technique used to determine the heights and visibility of texels. This method creates stronger relief depths. However, it does not allow for detailed detailing of objects.
• MIP-texturing is a method in which, when applying textures, copies of the same illustration of the texture are applied, with varying degrees of rendering of details.

Texturing with Viewport Canvas

In our work we will use a new feature of 3ds max – Viewport fitness Canvas. It seems that it was first introduced in 3ds max 2010, and was significantly improved in 3ds max 2011. If you do not have 3ds max 2011, then, unfortunately, you will not be able to complete this tutorial. Although if you have Photoshop, you could render the UVW template (Unwrap UVW> Parameters> Edit …> Tools> Render UVW Template …) and try to apply the principles themselves somehow. Anyway, let’s load Viewport Canvas and proceed to the coloring texture (PAINTING)
