We present a procedural framework for modeling the annual ring pattern of solid wood with knots. Although texturing is well-studied topic, there have been few previous attempts at knots inside texture. Our method takes skeletal structure tree log as input and produces three-dimensional scalar field representing time added growth, which defines volumetric pattern. First, separate fields are comp...

The effects of the texture coordinate precision to the image for procedural texture mapping is presented. In our project, we are trying to implement procedural solid texture mapping by hardware. By reducing the number of parameters for our texture mapping model and precision of texture coordinate, we can implement procedural texture mapping with small number of gates. We checked that how many b...

This paper describes a novel system for building seamless texture maps for a surface of arbitrary topology from real images of the object taken with a standard digital camera and uncontrolled lighting. In our application we wish to take a sparse set of real images of a 3D object, and apply the images to an approximate surface model of the object to generate a high quality textured model. In pra...

We propose a technique to project a synthesized texture onto 3D textureless real objects without contact, which can be applied for example, in medical or archaeological applications. Our system uses two cameras and one projector. By projecting a suitable set of light patterns onto the surface of a 3D real object and by capturing images with one or several cameras, a large number of corresponden...
