MMX Crib by Robert Rayment. For those interested in mixing VB & assembler. Demonstrates all the MMX instructions plus a few snippets. Win98 (exe WinXP) Zip 26 KB.

PlayOids2 by Robert Rayment. (2nd update, move shape to mouse click point) (Quick update to rotate in plane). Just a bit of maths play for those who like that kind of thing. Demonstrates rotatable wireframe spheres, ellipsoids,cylinders etc with and without perspective. Aspect ratio, perspective distance and animation variable on the fly and save as bmp. Zip 9 KB.

Digital Image Subtraction or Addition by Robert Rayment. (16th Mar. Correction to Save result) Combines two images by subtraction (Minus or Xor) or addition ( Whole Image or Edge Transparency). Subtraction only shows the difference bewteen two images and addition combines the images. The first image forms the base and the second, size equal or smaller than the base, takes the effects. Hand-scrolling is used rather than scrollbars, where the display is from a windowed array. Results can be saved as a bmp. Can run with Basic or MMX machine code. The machine code is held in a res file and the asm file included for reference. Couple of images included. CodeId=58968 has some subtraction images. dreamVB frames are used (CodeId=58966). Please see menu item Info. In particular the screen res needs to be >= 1024x768. Zip 189 KB.

Create/Edit Animated Cursors by Robert Rayment. As well as drawing the frames of an animated cursor, provides a set of step changes across the frames or a selected area for peppering, waving, swirling, squashing & Xfading. Frames can also be step changed for rotation and reduction. So this prog automates some kinds of animation. 1,4,8 & 24 bpp images can be handled. Some effects are included for 24 bpp images. Images can be loaded from ani, cur or ico files as well as captured from a bmp, gif or jpg. Title, author, number of frames, HotX & HotY and frame rates can be changed. For a new cursor any of the bpps can be selected. Some example ani-files are included. Cursors can be tested and saved at any stage. Please read the help for limitations. (Tested on Win98 & WinXP, Zip 82KB) (3 Oct Calc duration in frmDetails, system cursor preserved).

CUBOID CITY by Robert Rayment. Demo of what can be done with wire-frame cuboids, using pure VB & a couple of APIs for creating & animating scenes. Several thousand cuboids can be happily handled but make sure to compile the animation program!. Two progs, one to draw cuboid pictures (including random mazes) and the other to use the output files (*.ccc) and animate them. There are lots of options to help with drawing - too many to describe here. The animation program uses planar perspective for speed with mostly pure VB. Speed & direction set by distance of cursor from center of display, eye (camera) level and block heights changeable, collison detection and reaching the pyramid in the mazes explodes all. These progs provide a start for a full 3D wire-frame drawing program. Example ccc files included. See Notes. (Exe tested on WinXP) Win98. Zip 115 KB.

Digital Image Subtraction by Robert Rayment. (Updated: faster Basic routine, ASM action on Weighting & GreyLevel scrollbars) Demonstrates the power of MMX machine code which is at least 10 times faster than Basic in an optimally compiled EXE. See Info for limitations. Sample BMPs. Assumes MMX & QueryPerform.. APIs. Zip 123 KB.

PolyShader by Robert Rayment. (+ Stars) Demonstrates shading of regular and user defined polygons. Zip 36 KB.

Grey Options by Robert Rayment. Shows 8 different ways of changing an image to grey scale/effects (See code for descriptions). (Update BGR for RGB)(Zip 38 KB).

Beeper Madness by Robert Rayment. Plays 160 tunes through the PC speaker. Crazy! (Not Win98, Zip 143KB)

Brick Play by Robert Rayment. UPDATE: picture size handle added (idea from Loc Nyguyen's VB Paint). Produces a variety of brick patterns that can be saved as BMPs. __________________________________________________ Pure and simple VB apart from a bit of blitting and a touch of timing (Assembler Not Included). Zip file 10 Kb.

Spinning Illusions by Robert Rayment. (Small change, hopefully more stable on other OS than Win98) Just a bit of VB doodling, 8 shapes with odd effects. [ Shaped form & picbox, +/- rotation anti-alias rotation, VBASM, Res wav ]. Zip 100 KB, Win98.

I love pencil drawing and there's nothing to beat pencil and paper. On the computer the mouse never moves as easily as a pencil but mathematics does allow some types of drawing to be carried out much more quickly than would be possible by hand. This is a pencil drawing programme with 256 shades of grey. It has 21 drawing tools and a host of sub-tools all easily selected from on-screen toolbars. Many shaded shapes such as curved lines, tubes, cones etc can be drawn. All the standard picture formats can be loaded or added and re-positioned. Saving is either as a BMP or a JPG file. Any rectangular part of the picture can be saved. JPG saving and printing is accomplished by using a single exe, free-standing, freeware conversion program that takes a command line and is hence easily used in VB. The source and credits for this are included in the .zip file In addition to the tools there is a zoom facility, whole-picture scrolling, +, X & perspective hair-lines, settable brick & tile sizes, text with any font, size or angle, undo and two canvas sizes suitable for A4 paper. All the source files, including button bitmaps, are included. The .zip file is just over 1MB and the program is written for an 800x600 screen.

BRRIC by Robert Rayment: (Corrected for 2-color bmp & ico 14/01/03) This program deals with pairs of icons (16x16 & 32x32, 1 bpp to 8 bpp), small bitmaps (1 bpp to 24 bpp) and 32x32 cursors (4 bpp). A large number of palettes can be loaded. Many image manipulation controls are included eg drawing tools, blurr, rotate, text etc. All the controls include ToolTipText. My personal preference is to have as many controls on-screen rather than buried in menus. This is not to everybody's taste and the screen will look cluttered but is much quicker to use. Icons can be extracted from multiple icon files and the system icons from exe and dll files. Small 32x32 rectangles can be extracted from larger bitmaps. The use of a res file for bitmaps and binary data is demonstrated. Win98, Zip 170KB.

RR3D: Displays a rotatable and scaleable wire frame of any 3D mathematical function. This can be made up from the normal VB maths plus inverse and hyperbolic functions. Functions can be created and saved as wanted. Image vertices can also be saved for use elsewhere. The MS ScriptControl Eval function simplifies calculations enormously and its use is demonstrated. Also shown are MoveToEx, LineTo which are much faster than the VB equivalents and very easy to use. Included are a set of string handling subroutines such as count characters, squeeze out spaces, replace sub-strings etc. Commented throughout including the 3D maths and perspective methods. All the files are visible and the program is written for an 800x600 screen.

Shove H'Penny by Robert Rayment. (Updated for XP)An old English pub game. The full rules are applied including illegal moves - see help file. The hardest part was getting a reasonable collision between disks: a bit of distorted Newton plus blitting, constructive comments on this welcome. Win98, Zip file 56 kb.

RRCalc by Robert Rayment: (UPDATE Now stays on top) Not another calculator I hear you say. But I have this one on my Office bar and find it easier to see and use than the MS Standard calc. It has the usual numbers and arithmetic operators plus square root, square, reciprocal and pi; memory clear, store, add and recall along with a window showing what's in memory. All the buttons can be operated with the mouse or the keyboard. The zip file is 31KB.

Plasma Worlds by Robert Rayment. (Cylindrical tunnel added to ASM version)Two progs. One, pure VB (no APIs or OCXs) for making plasma screens that can be saved as a bmp, bit slow but adequate when compiled. Plasma uses a non-recursive routine on to any rectangle and can be wrapped for tiling. Graininess, scale & color palettes can be changed. The other prog is the same PLUS scrolling in 16 directions, color cycling, cylindrical, spherical & hyperbolic wrapping and fantasy landscape projections all with multiple controls - VB+APIs+ASM, much faster. Only tested on Win98, should be OK on ME & XP but some Win2K OSs have problems with this use of Assembler. Please let me know your OS if you find bugs. Zip 79KB.
