erm, ok, thats weird

waving the mouse around stops it from crashing :S

The only place in the source where I use the rotten TGA reader is during preparation of the GUI skin, and since the GUI graphics is the only stuff that is actually sour perhaps the problem could be solved by using DevIL for loading themefiles.

I'll post some new code tonight.

Also I will be postponing 0.0.4 until various small things have been fixed, such as better shutdown.

centipede · Post by **centipede** » Mon Feb 27, 2006 9:53 pm

This package here may start up a little better. Jacmoe, I get the string exceptions too - probably related to dirty shutdown - so it shouldn't be too hard to get rid of them.

http://artcamilla.dk/centipede/bughunt/bugcircus8.zip

Please note, that the theme files have changed (from .tga to .png otherwise DevIL wouldn't cope). So be careful when mixing things.

I removed the no-shader version as people seemed to be ok with the shaded one. Ask if you want a non-shader .exe compiled.

Post by **jacmoe** » Mon Feb 27, 2006 9:55 pm

What do you want me to do with it?

<edit>
OK. I ran it.
Nice startup without the need for frantic mouse movement. No exceptions, ever.

Smooth painting of the cube.
Although the cube is not rotating real-time, it is easier to control it.
Nice!

</edit>

<edit_again>
I hope the switch to DevIL fixes the ugly interface rendering @Slicky's.

Yup, it's getting better and better ^_^

(btw.. i think the output has stretched UV's...)

Nope window rendering is still unreadable using the 2/27 9:33pm exe.

edit: fyi the program starts windowed. Even if I toggle it to full screen it doesn't seem to fill the maximized window. I am running my desktop at 1920x1200

Sorry for the silence, I have a total of 5 hours of busrides per day and I'm already starting to get a low immune defense from not working on REAL things

@ people with slow updates (both nvidia and ati):
Found something on the opengl.org forums about performance drops if AntiAliasing is turned on. On some (older) systems it seems to take a big hit on functions like glCopyPixels. E.g.

Code: Select all

Radeon 9600 Pro results.

No FSAA:
glCopyPixels 867
glDrawPixels 51
glReadPixels 104

4X:
glCopyPixels 59
glDrawPixels 51
glReadPixels 39

6X:
glCopyPixels 60
glDrawPixels 51
glReadPixels 39

Catalyst 4.10.

Could you tell me if you have AA turned on in some kind of driver control panel?

EDIT: Testresults on my system with this program by Adrian on OpenGL.org: www.adrian.lark.btinternet.co.uk/GLBench.htm

Code: Select all

No FSAA:
       glCopyPixels 2793
       glDrawPixels 790
       glReadPixels 167
  glReadPixels(PDR) 194

FSAA 8xS:
       glCopyPixels 0
       glDrawPixels 813
       glReadPixels 16
  glReadPixels(PDR) 16

0.0.4: Undo/redo + face selection

http://artcamilla.dk/centipede/insects/ ... -0.0.4.zip

Needs testing

Did anybody read the posting above this one? I'm not investigation further in on the slowness problem before people can confirm that they have antialias switched off (i.e. the control panels "let the program decide" option)

Slicky · Post by **Slicky** » Sun Mar 05, 2006 9:21 am

I see triangles on the cube but can't draw on it.

centipede · Post by **centipede** » Sun Mar 05, 2006 10:31 am

Space: Toggle between face-selection and draw mode. Ctrl-Z and Ctrl-Y are the undo/redo buttons.

Ok, my experience so far:

- It's still really slow.. i've turned off all AA options of my drivers.. but still the same speed (maybe add a little fps counter in the corner?)
Also.. this system isn't quite old, it runs a Ati X850Pro on a Amd64 3200+, windows xp (32bit) with 1gig ram.

- Selecting faces works, however, when deselecting all of them, i cannot paint anymore on the surface. (edit: nm, i can't paint anyway on the surface, only after having selected a face.)

Ctrl+X works here as undo.. redo doesn't seem to work here.

and the log:

That is so ODD?!?! Try this exe, use only these keys: Space, Control+Z, Control+Y and in that order. Post the log and I can see what happens in the input system. Odd odd odd. http://artcamilla.dk/centipede/bughunt/bugcocci1.exe

I've seen the program on an ATI X14000 (or whatever, laptop) and it crawled so slow. I believe your statements, just had to make sure it wasn't AA or anisotropic filtering.

centipede · Post by **centipede** » Sun Mar 05, 2006 1:59 pm

IFASS and Slicky, could you run this program and save the results?

http://artcamilla.dk/centipede/bughunt/glinfo2.zip

Also please try this exe. No change except it sets the pixelformat to use 32-bit instead of 24 bits. I take it your desktop resolution is 32 bits, right?

http://artcamilla.dk/centipede/bughunt/bugcocci2.exe

EDIT: ... And thank you for the help! Do you want your real names in the credit list or just your handles?

Post by **jacmoe** » Sun Mar 05, 2006 2:52 pm

Both binaries are OK on my computer.

I think the new select before painting is cumbersome, but it works.

centipede · Post by **centipede** » Sun Mar 05, 2006 4:21 pm

I tried painting on a few models of just modest complexity, and there's no doubt that I have to have a way of making sure the paint stays where it is intended to do. But there are definitely other ways, though they tend to be much more advanced. For instance if the user starts to paint on a given face and moves the mouse, the editor should 1) turn the object to make sure the brush always face directly into the surface, and 2) only allow painting on faces that are directly connected to one that has just been touched. That way you avoid "missing" the stem of a high tree and splatter leaves on the ground.

This version works but the selection of a side/triangle seems to take 2-3 seconds and rotation is very slow.

I'm not sure if a normal selection is a triangle. It seemed that sometimes I had a square side selected.

My desktop is 32bit.

I think I can borrow an ATI 9550 soon. Hopefully I can reproduce the problems people have.

centipede · Post by **centipede** » Fri Mar 10, 2006 9:17 am

On monday I will get the aforementioned board for direct testing. Seems most ATI systems has the same issues.

Next feature being focussed on is the possibility of working on multiple objects in one scene which brings me to the question of whether the DOT-SCENE format is still in use. If memory serves me, there are two utterly different dot-scenes: An XML file with names and positions of scene nodes, and the newer octree-like thing. Is this all wrong?

So, if you would recommend a good format for complete scenes (it's okay to spread the information across several files), could dot-scene be it? Will it work with the Blender exporter?

I think this very same problem will also be relevant when it comes to materials. I have prepared for a multi-layer (hierachical layer actually) material system where you can actually move the individual layers about. I doubt there is any suitable format for expressing this, but please utter your knowledge about such matters.

P.S.: This will not develop into a scene editor - already good ones around, I believe.

IFASS · Post by **IFASS** » Fri Mar 10, 2006 2:34 pm

Painting on complete scenes would be great for example painting roads.

DotScene.. look at yake.org , afaik that one is most used.

Good. Looks safe to conclude that the hierachichal dot-scene format is still going strong.

About multilayered materials: If a material script with multiple passes is interpreted as an image with several layers, then perhaps that fileformat could be used to describe multilayered textures, but ofcourse not hierachical ones, i.e.

Code: Select all

Image                                    
  |                                      
  +------- Layer1                        
  |          +------ Layer1.1            
  |          +------ Layer1.2            
  +------- Layer2

However, I doubt that it is possible to position the layers independently. That would require each pass to use it's own texture coordinates.

Look at me, I'm driving ATI, woooiii

..And oups, slowness problem is fixed. I REALLY REALLY REALLY REALLY got to remember to keep away from non-power-of-two textures, both as a render target and source. It was the gui theme texture that slowed things down. Resizing from 800x1000 worked like magic. There's still a few odd-size textures left here and there, but to begin with, this will do.

Hopefully I can borrow this ATI Radeon 9600 (9550?) for a little while further. Seems like an appropriate choice for developing things.

Haha, you gotta be kidding me

Nice you solved it though

Edit:
Wow.. it works really great now!

Wow! This is fast! This is real-time! Great job, centipede!

I do get some rendering artifacts which is really difficult to show on screenshots.
I will make a movie tomorrow evening using Fraps to show you how it looks.
