IPAS Questions
Message #90173
Hi Jonas, Any word on the questions I posted a couple of days ago? I could use the answers right about now. Talk to you soon, Danny…
Hey Robert, I'll give you a call. What time zone are you in? I live in Toronto – Eastern Standard Time. I don't want to risk calling you in the middle of the night! Talk to you soon, Danny…
> I think in summer we`re in the movies. Congratulations! Good luck on your project. I look forward to getting your "nice program". Talk to you soon, Danny…
> If you have any beta stuff you'd like to see on TV, let me know, and we'll see if we can work it into a proposal. Very interesting! Maybe we should take this to email? We can talk a bit more there. Regards, Danny…
Hi Michael! How's the project coming. Don't worry, you've been on my list for a long time. Talk to you later, Danny…
I looked for it yesterday but I guess it hadn't been posted yet. I'll go have another look right now. Danny…
KXP Object Manipulation
Message #89454
Does anyone know whether it's possible to use something like 'pxp_put_verts' and 'pxp_put_faces' from within a KXP? I was going through the documentation for KXPs and saw that there were references to 'kxp_get_verts' and 'kxp_get_faces', but nothing that referred to 'putting' mesh object info. I'm trying to write a program…

BLOB MODELER???
Message #89249
I'm currently working on a metaball modeller for 3D Studio. I hope to have some sample images and animations available to post here soon. Regards, Danny…
ItemMesh Flags
Message #89202
Hi Jonas, OK, so you can't set the flags variable of a mesh object…. Can you determine whether an object is selected? When I try to access 'idata.item.m.flags', all I get is zero. Does this mean that you can't access the flags at all? If that's the case, how can…
Pxp_create_item Sample
Message #88345
John, I figured it out last night. I was not addressing the XVData and XFData structures properly. Anyhow, after I figured out what I was doing wrong, I managed to build my app in about 3 hours. I now have a functional PXP Metaball Generator. All I have left to…
Hi John, > I've made faces via the function call interface, and I uploaded a few snippets. Is that what you're looking for? Yes, that's what I'm looking for. Are these bits of code available here or did you send them directly to Gus? > After you've loaded the object,…

Pxp_create_item Sample
Message #87495
Hi all, Is anyone getting tired of my constant questions yet? If not… Does anyone have some sample code or code snippets that demonstrate how to perform a pxp_create_item using pxp_put_vert and pxp_put_face? I can create objects in the editor using the burst mode commands but I'm finding the direct…
Y/Z Obj Extents Flipped?
Message #87494
Thanks for the explanation about the Y and Z flipping in the 3ds.set file. Danny…
EXP_SELECT_INPUT_OBJ
Message #87493
Thanks Grant, I didn't realize that the I could use values from the matrix. Works fine now. Regards, Danny…
I mean the center of the object. Danny…
The trouble with trying to use ItemMesh.mins[] and ItemMesh.maxs[] is that they return the extents of the objects itself, with the origin being the center of the object – not the world origin. In other words, this returns the size of the object but not its position. Using this approach…
EXP_SELECT_INPUT_OBJ
Message #87117
Hi Folks, In the EXPRTN.H file there is a reference to EXP_SELECT_INPUT_OBJ that states that it is available to both PXP and AXP routines. The command is defined as follows: #define EXP_SELECT_INPUT_OBJ 0x2020 /* Use specified named obj as input */ However, when I try and use this command in…
#Scanning Objects
Message #87106
Hi everyone, Here's another annoying little question: How does one go about scanning all the objects in the editor? I'm trying to perform an EXP_OBJ_EXTENTS on all mesh items in the editor and putting the relevent info in a database. Unfortunately, the only way I've found to set the current…
Y/Z Obj Extents Flipped?
Message #86943
Hi folks. Has anyone noticed that the min, max, & center values for the Y and Z axis components of EXP_OBJ_EXTENTS (ExtInfo) are flipped? I've tried this with several different types of objects and the miny, maxy, and centery components are always exchanged with the minz, maxz, and centerz components.…
Thanks Jonas, Have a great weekend!
Yes. Please do post it here. I'd very much like to have a look at the direct call code that Tom came up with.
Martin, > you are a 3d stud! Thanks! For a while I was afraid I only existed in 2D. My wife will certainly be relieved! Danny…
Robert, > I'll be looking for a spaghetti IPAS to go with your Metaballs. And maybe some "Yost-Group-particle-system-parmesan" on top! Ciao, Danny…
Hi Ara, It may be totally sick but it should also be totally fantastic!! I can't wait to get my hands on some of the stuff that will be appearing. Regards, Danny… (P.S. I'll let you know when the Metaball modeller is ready.)
Stay tuned for an IPAS3 Metaball or "blob" modeller. I should have it ready soon. Core code written, just working on the port to IPAS. Regards, Danny…
Jonas, Gotcha. Thanks, Danny…
Thanks Jim, That's pretty much what I figured. Danny…
I'm not referring to changing an object's colours, etc. That stuff works. I'm talking about the the ItemMesh flags. eg. MESH_FROZEN MESH_SELECTED MESH_MATTE, etc. I saw in the documentation that this might be fixed in a point release of 3D Studio. I take it that this is still the case…
Samples
Message #85856
1) Are you guys going to post sample code using the new functions in this forum? 2) Has there been an update since the last one I received. (You know about the time lag of stuff getting to me. ) Talk to you later,
#Item Flags
Message #85854
Being all the way up here in Toronto, it takes a little longer for me to get the SDK updates than you folks in the States. Could you guys tell me, have the pxp_change_item Item Flags been enabled yet? Danny… P.S. I like this new forum!
Judy, Try using the Plasma IPAS on your fireball. Set the texture of the plasma tendrils to use a semi-transparent smoke sxp and animate the texture as well as the tendrils. Should work fine. Regards, Danny…
I was afraid I was being too long-winded!

Flock, Skel-skin IPASs?
Message #75346
Hi Eric, Yes, that's exactly what I'm working on. In addition to what John T. said, see my message to James Tichenor. It will explain a bit about what I'm trying to do. Regards, Danny…

#a poll
Message #75345
OK, a little background on beziers… A bezier is a 2 dimensional parametric representation of a curve based on 4 control points; 2 end points and two mid points. By moving the control points relative to one another, the shape of the curve is changed. This method of creating curves…
Hi Dan, Umm, which IPAS routine are you referring to? I'm currently working on three of them. Regards, Danny…
The metaballs will indeed be converted to a mesh model. That will allow for standard texture mapping within 3D Studio. I agree about letting the user determine the face count. Obviously, there would have to be some minimum number based on the number of blobs and their interactions, etc. but…
> you get my vote for "man (or woman) of the week" "man of the week" please. Danny…
OK. I understand where you're coming from now. I agree that texture mapping of any complexity is a MAJOR undertaking for metaballs if they remain in that state from the modelling to rendering stages. What I'm trying to write is a "metaball" modeller which deals with objects as blobs during…
> It would be fun to have metaballs technology for 3DS for liquid forms, but its application without some ability to texture map would be limited IMO. What do you mean by "ability to texture map"? If the blobs exist as objects in 3D Studio, it should be as easy…
Thanks Ana, I'd appreciate whatever info you can get a hold of. Merry Christmas, Danny…
> Is the 3d bezier patch generation program equivalent to a NURBS modeler, like Alias et al? Well, yes and no. Why yes: The core of the adaptive bezier patch code was co-developed by me and a friend who works at Alias here in Toronto. Actually, he's "Team Leader -…
Hey Paul, Were you able to locate some people for those animation positions you advertised a while ago? I hope things work out well for you on that project. > Sounds like you've got alot of work ahead of you. Too much work, actually. This is the third 3D Studio…
Yup, I'm working on it. It will conform not only to attraction levels but repulsion levels as well. That means you can have blobs create "dents" or "dimples" in other blobs based on proximity and size. In other words, blobs can flow together or push apart based on their individual…
Strangely enough, I'm also working on a "blob" or "metaball" generator for 3D Studio. Do you have any more info about these people? Do they have any samples available? Regards, Danny…
Norbert, There will soon be an IPAS program I wrote which should do what you're looking for. Unfortunately, it won't be available for a few weeks. Can you wait that long? Regards, Danny…
#RGG Status
Message #70958
Over the past two weeks, a fair number of people have been calling, and sending email and forum messages asking about the status of RGG – the Raw Globule Generator for 3D Studio. Well, RGG has successfully made it through the beta process but it won't be available for a…
Steve, RGG (Raw Globule Generator) is in final beta right now. I'll post a message regarding its status soon. Thanks for your interest, Danny…
Thanks Keith, I'll look for it at the university book store. Regards, Danny…
