If you are unaware of MIME types for Chemistry which are required of MAGE click here About these activities: MAGE and PREKIN are software packages used by scientists to assist them in understanding molecular structure and function. PREKIN allows the user, starting with a set of Cartesian coordinates, to create a database that can then be displayed as an image using MAGE . The images (referred to as Kinemages) can be manipulated in 3 Dimensions. In addition, it is possible to perform distance and angle measurements on the objects as well as draw new lines that can be incorporated into the image. These capabilities make MAGE and PREKIN an excellent tool for use in K-12 mathematics and science. We have used PREKIN and MAGE to create five introductory databases that contain images found in the K-12 mathematics and science curricula. We are presently developing and testing activities to be used with these databases. We feel the use of these software packages, in addition to other public domain software found over the Internet, have several interesting features for use in K-12 education, amoung them:

The original question asked was: Calling the Triangulator constructor with an argument of 1 (EARS_RANDOM) will produce a different triangulation than that produced by GeometryInfo on its own, so the Triangulator object obviously does do something, but it seems that the default Triangulator (with no arguments to the constructor) just produces the same results as if it hadn't been called at all. The reply posted by Paul Pantera of Sun is: To further expand this, the NormalGenerator and Stripifier only work on indexed triangles. Therefore, no matter what format your data is in, it will be converted to indexed triangles if you call the NormalGenerator or Stripfier. This is hidden from the user. If you send in quads and call the stripfier, you will get triangle strips out, and you won't know that your quads were converted to indexed triangles in the interim. So the answer to your question is yes, you don't need to call the triangulator explicitly (unless you want to specify the earOrder) because it gets called automatically when POLYGON_ARRAY data is used. Does it hurt to call it explicitly? Not much. The triangulator is smart enough to do nothing if the input data is already triangles.

Posted by Chien Yang of Sun The Java 3D API was designed with high performance 3D graphics as a primary goal. This document presents the performance features of Java 3D in a number of ways. It describes the specific APIs that were included for performance. It describes which optimizations are currently implemented in Java 3D 1.3. And, it describes a number of tips and tricks that application writers can use to improve the performance of their application. Performance in the API There are a number of things in the API that were included specifically to increase performance. This section examines a few of them. Capability bits Capability bits are the applications way of describing its intentions to the Java 3D implementation. The implementation examines the capability bits to determine which objects may change at run time. Many optimizations are possible with this feature. isFrequent bits Setting the isFrequent bit indicates that the application may frequently access or modify those attributes permitted by the associated capability bit. This can be used by Java 3D as a hint to avoid certain optimizations that could cause those accesses or modifications to be expensive. By default the isFrequent bit associated with each capability bit is set.

Geometry of Linear Transformations of the Plane Let V and W be vector spaces . Recall that a function T:V W is called a linear transformation if it preserves both vector addition and scalar multiplication: T( v v T( v ) + T( v T(r v rT( v for all v v V. If V = R and W = R , then T:R R v ) = A v for all v R . Matrix A is called the standard matrix for T. The columns of A are T [ 1 ] T and T [ 1 ] T , respectively. Since each linear transformation of the plane has a unique standard matrix, we will identify linear transformations of the plane by their standard matrices. It can be shown that if A is invertible, then the linear transformation defined by A maps parallelograms to parallelograms. We will often illustrate the action of a linear transformation T:R R by looking at the image of a unit square under T. Rotations The standard matrix for the linear transformation T:R R that rotates vectors by an angle q is A = cos q -sin q sin q cos q This is easily derived by noting that T cos q sin q T -sin q cos q Reflections For every line in the plane, there is a linear transformation that reflects vectors about that line. Reflection about the x-axis is given by the standard matrix

39. KevLinDev - Tutorials - Geometry To my surprise, these complex curves can be plotted using a simple geometric approach. This tutorial describes this approach for rendering 3 rd order Bezier http://www.kevlindev.com/tutorials/geometry/bezier/

Home Tutorials :: Geometry Convex Hulls and Mid-Points Plotting the Rest of the Curve Points Other Than the Mid-Point Recursion with Depth ... Example of Potential Use Introduction Convex Hulls and Mid-Points To describe the curve, the user places four points called control points. The curve passes through the first and fourth control points. The second and third control points act as magnets for the curve. The curve never actually passes through these points. Now we find a single point on the curve using these four control points. First, we draw the convex hull of the curve by connecting the control points in the order they were drawn. Find the midpoint of each line segment that we drew. Connect these points to form a new hull. Find the midpoint of each of these new line segments. Connect these two points. Finally, find the midpoint. This is the point found at the middle of the curve. The last line used here is a tangent to the point found on the Bezier curve. This tangent can be used to calculate a stroke for the final curve. As seen in the examples below, I've added perpendicular lines to each point found in the curve. If you imagine connecting all of the line endpoints by traversing them in a clockwise or counter-clockwise order, you can see that a thicker (or stroked) version of the skeleton Bezier will result.
