Un-optimised and needs work, but in principle it shows what is possible. [Mike]  1194349979_671_FT0_wibblywobbly.zip Editor of \'Voice of the PPL\' the newsletter for the PPL by the PPL!

I am still on Version 1.32 Pro and it works on both my home PC and work PC (30 day trial) No special location, just unzip and away. Home PC still running Vista and Work PC still running XP Pro.

If you don't want to send me the source code just send me the .PPC file. It could be that something has changed since 1.32 (and we all know a lot has changed)  Regards, Alain Deschenes President and programmer ArianeSoft Inc. (http://www.arianesoft.ca) | ||

| Registered Member #1 Joined: Wed Apr 19 2006, 08:25pmPosts: 2783 | This one works perfect. Btw, here is a little trick, try to make all processor intensive calculations in the WM_TIMER event instead of WM_PAINT. Try to keep WM_PAINT for just drawing things to screen. You should use a temporary surface that you draw onto in WM_TIMER and draw it to the screen in WM_PAINT. This way you will always be getting the same framerate, on fast and slow computers. I know the FPS is limited to 60 frames per second but on the PocketPC this could be one of the reasons why it is slow. Try to stay away from FOR() loops as well in time sensitive loops, use WHILE() loops which is much faster. These are little tricks that will help speed up your program a bit.

  Registered Member #10 Joined: Sun Jun 18 2006, 09:41pmPosts: 107 | Mr Mike!!! I'm impressed. I can forsee a "form transistion" library being written where a grap of the current screen is made to a surface, the resulting surface transformed (swirled, flipped, etc) and the new form displayed in its place.

Perhaps in next month's newsletter? You only stop learning when you die. Sometimes I think I am dead http://www.don-simmonds.co.uk | ||

| Registered Member #671 Joined: Tue Sep 25 2007, 12:22pmPosts: 400 | Well, as a matter of fact ... The optimisations Alain has suggested have speeded the routine up by about oooo .. 20 times! hee hee I will be featuring an combined optimisation and surface tutorial in Dec 07 newsletter so keep watching. This routine was really easy once I understood how the surface generation and displaying worked. - Donone - I'm sure its not mearly dreams .. all you need is a good idea, and a few carefully placed questions on the forum.

| Registered Member #671 Joined: Tue Sep 25 2007, 12:22pmPosts: 400 | Andrew, I can see a real use in 3D routines as the DRAWSURFACE3 command has an angle option. Hmmm texture mapped faces maybe? But if not, then a form transition library woudl surfice. Any volunteers to do a form or screen manipulation/transition library then?

| Registered Member #10 Joined: Sun Jun 18 2006, 09:41pmPosts: 107 | I started the library... I'll have a proof-of-concept in a week or so (probably right after Thanksgiving here in the States) I'll offer a standard transisition function that you feed start/end form handles and transition type... initially "type" will be limited to one or two but will expand over time Let us not love with words or tongue but with actions and in truth -- 1 John 3:18 | ||

Optimisations performed by moving the sine calc to the WM_TIMER: section from the main drawing section. Much faster and a more contstant frame rate.

| Registered Member #671 Joined: Tue Sep 25 2007, 12:22pmPosts: 400 | doh - forgot to include the bitmap in the .zip files. You can use the logo from the original post - that should be fine. Q: any reason why attachments show as having a space in them? wobblylogooptimi sed_small etc, etc??? Is this just happening in my browser?
