There are four basic types of CSG operations: union, intersection, difference, and merge. CSG objects can be composed of primitives or other CSG objects to create more, and more complex shapes. Inside and Outside Most shape primitives, like spheres, boxes and blobs divide the world into two regions. One region is inside the object and one is outside. Given any point in space you can say it's either inside or outside any particular primitive object. Well, it could be exactly on the surface but this case is rather hard to determine due to numerical problems. Even planes have an inside and an outside. By definition, the surface normal of the plane points towards the outside of the plane. You should note that triangles and triangle-based shapes cannot be used as solid objects in CSG since they have no well defined inside and outside. Note: : Although triangles, bicubic_patches and some other shapes have no well defined inside and outside, they have a front- and backside which makes it possible to use a texture on the front side and an interior_texture on the back side.

Unfortunately the letters N, A, and D are not as amenable to this as the letters G, E, and B: notice that the shadow of the N has a slight curve at its top right, owing to the N's intersection with the curve on the D and the slope on the A. Various other arrangements of the three letters were tried, all of which gave more noticable artefacts than this. Each of the letters is a CSG object (the D, for example, is constructed from cylinders and boxes). The final effect is produced simply by intersecting the three letters.

Next: CSG in Rayshade Up: Object Definition Previous: Aggregate Objects Constructive Solid Geometry Constructive Solid Geometry is the process of building solid objects from other solids. The three CSG operators are Union, Intersection, and Difference. Each operator acts upon two objects and produces a single object result. By combining multiple levels of CSG operators, complex objects can be produced from simple primitives. The union of two objects results in an object that encloses the space occupied by the two given objects. Intersection results in an object that encloses the space where the two given objects overlap. Difference is an order dependent operator; it results in the first given object minus the space where the second intersected the first.

Next: 8.4.1 Union Up: 8 Using the Stencil Previous: 8.3 Finding Depth Complexity 8.4 Constructive Solid Geometry with the Stencil Buffer Constructive Solid Geometry (CSG) is the process of building complex solids from logical combinations of simpler ones [ ]. Basic logical operations, such as union, intersection, and inverse are used as relationship operators between pairs of three dimensional solids. In these algorithms, the solids are assumed to be defined by closed surfaces composed of polygons. The polygons composing the primitives are defined in a consistent way so that the front face of each polygon faces out from the surface. CSG is used as a method to create complex solids as part of a computer aided mechanical design process. Constructive solid geometry can be created using the stencil buffer functionality. It can be thought of as a ray-casting technique, counting the intersections the pixels of an solid's surface makes with other surfaces as it's projected onto the screen. The techniques shown here are image space techniques and are limited to visualizing CSG solids. They don't produce a list of vertices that could be used for further processing. They also tend to leave the depth buffer with values that don't match the visible surfaces. As a result, CSG solids often can't be used as components of a complex depth-buffered scene. Creating CSG solids is a multipass technique. Two objects are chosen, and the desired boolean relationship between the two is discovered. The basic CSG stencil operation is the ability to find the part of one solid's surface that exists in the volume defined by another solid. Pieces of each solids surface is progressively rendered, until the entire solid is completed. The solids created with CSG are rendered as pieces of the surfaces of component solids; no new surfaces are created.

The tree formed by the binary CSG operators and their operands is known as the CSG tree. Figure shows an example of a CSG tree and the resulting model. The representation used in CSG for solid objects varies, but we will consider a solid to be a collection of polygons forming a closed volume. ``Solid'', ``primitive'', and ``object'' are used here to mean the same thing. CSG objects have traditionally been rendered through the use of ray-casting, which is slow, or through the construction of a boundary representation (B-rep). B-reps vary in construction, but are generally defined as a set of polygons that form the surface of the result of the CSG tree. One method of generating a B-rep is to take the polygons forming the surface of each primitive and trimming away the polygons (or portions thereof) that don't satisfy the CSG operations. A B-rep models are typically generated once and then manipulated as a static model because they are slow to generate. Drawing a CSG model using stencil usually means drawing more polygons than a B-rep would contain for the same model. Enabling stencil also may reduce performance. Nonetheless, some portions of a CSG tree may be interactively manipulated using stencil if the remainder of the tree is cached as a B-rep.

[an error occurred while processing this directive] Next: Boundary models Up: Constructive models Previous: Half-space models Constructive solid geometry In CSG, solids are described as combinations of simple primitives or other solids in a series of Boolean operations, i.e. a CSG model is constructed using a so called building block approach. A user operates only on parameterised instances of solid primitives and Boolean operations on them. Each primitive is defined as a combination of half-spaces. The construction of CSG models is exactly the same as in half-space models, except that only finite sides of the half-spaces are included. Using Boolean operations on finite solid primitives, the resulting solid is always guaranteed to be finite as well. Any primitive for which all the operation procedures can be written can be included into a CSG modeller. A normal addition to a CSG modeller is sweeping primitives. For example, a translational sweeping primitive is defined by a bounded face and the sweeping vector. Typical standard primitives are cone, cylinder, sphere, torus, block and right angular wedge. Operations are union, intersection and difference. Other CSG primitives are swept solids, i.e. a revolution or linear sweep of a planar face which may contain holes. Composite CSG solids may also be subjected to Boolean operations. Using a Boolean operation, a new solid is constructed from two intersecting solids. This technique is common in mechanical engineering since it gives a precise, analytic description of the model. The convenience of a CSG modeller depends on the set of primitives and Boolean operations available. A simple CSG model with a Boolean subtraction is shown in Figure

Next Constructive Solid Geometry When the hardware accelerator provided by Apple Computer, Inc., is available, the interactive renderer can support constructive solid geometry (CSG), a method of modeling solid objects constructed from the union, intersection, or difference of other solid objects. For instance, you can define two cubes and then render the solid object that is the intersection of those two cubes. Similarly, you can define three cubes and render the solid object that is the union of two of them minus the third. For example, Figure 3 shows three cubes ( A B , and C ) together with the result of using CSG to create the solid object defined by the function ( A B C In this chapter, CSG operations are described using standard set operators: the operation A B is the set of all points that are in both A and B (that is, the intersection of A and B A B is the set of all points that are in either A or B (that is, the
