DeleD Community Edition

[Akira13]

For anyone that isn't aware, in 2013 JuhaManninen (a moderator at the Lazarus forums, i think) ported DeleD from Delphi to Lazarus. Originally, as you all know, it used dglOpenGL with a custom "TOGLForm" class that was native to the application. As far as I know he did get it 100% working with the original method of rendering, but then after beginning to attempt to move it over to use Lazarus' TOpenGLControl he stopped working on the project for one reason or another. So it's pretty much been entirely stagnant for the past view years with the TOpenGLControl implementation very much not working at all. I decided to pick up where he left off a couple of weeks ago, and I'm happy to state that I've pretty much got the entire application "working as intended" with TOpenGLControl (as in no more dglOpenGL anywhere.) I don't think I'm quite ready to post the updated codebase anywhere yet, but I certainly will once I get it cleaned up a bit more. Apart from getting it to work with TOpenGLControl at all, other significant changes I've made are:

-Replaced all of the outdated SendMessage and PostMessage stuff with proper LCL event handlers
-Fixed the Raytracer and Screenshot manager save-to-image-file functionality (the resulting files aren't just entirely black now! ;D)
-Fixed some weird TList-related bugs that would cause certain aspects of the applications functionality (like the Hollow and Smooth Tool) to make it crash to desktop
-Replaced all the TControlBars with TPanels (TControlBar is just extremely buggy, and isn't a unique or important enough component relative to the applications functionality to be worth spending time fixing)
-Added an anti-aliasing level control so you can make the viewport look nice!
-Other misc stuff that i'll detail more later.

Here's a preview screenshot of the application running with eight-times multisampling:

Hey Akira13, welcome to these forums! You've been quite busy with the port - good job! I can imagine this was a lot of work. What are your plans with it from this point?

That is fabulous! Thanks Akira13.

Akira13, do you need help with revision control systems?

[Akira13]

I don't know if anyone still monitors these forums, but in case they do:

I've made quite a few more improvents since the last time I posted here, and am aiming to upload my changes sometime tomorrow.

A few highlights:
-User controllable anti-aliasing settings (applied to all viewports)
-Full support for textures in ALL common image file types and pixel formats (16bit, 24bit, 32bit, whatever you want... it no longer matters at all)
-Built-in native OBJ exporter
-Significant performance improvements application-wide
-Revamped windowing system (the application now uses a fully customizable "docking" implementation, facilitated by the Lazarus "AnchorDocking" package)

Refer to this thread on the Lazarus forums for more information, if you're interested:

Here's a screenshot:

Wow that's awesome progress there, Akira13! Is there an .exe we could download? Would love to play with it.

That's always interesting. Like Jeroen said, is there a exe we could download to check things out?

Hey guys. My sincere apologies for falling off the face of the Earth. I've just been extremely busy with my actual real-life job, and with continuing to work on DeleD in what time I've had in the interim. That being said, how does the idea of DeleD actually rendering scene lights as real OpenGL lights in real-time sound? Hopefully good, because it's a thing now!



The selected pointlight in that screenshot is the only active lightsource. There are no lightmaps or other texture trickery of any kind present whatsoever. (Other than the fact that I've obviously replaced the original low-res textures themselves with high-res ones, but that has nothing to do with lighting at all.) Basically how it works now is I've added checkboxes in the main options menu that allow you to toggle the use of either the classic infinite sun light DeleD has always had, or scene lighting as shown in the screenshot, or a combination of both, or neither. Also, in case you're wondering, "but what if I want to take a screenshot without the light bodies visible!?!?" you can. You can freely turn off the rendering of the red placeholder meshes the same way you always have, and the effects of the light will remain visible for as long as the light itself exists in the scene (i.e. until you delete it.) Now, as far as the EXE of the application some people were asking about, I'll try to get one up relatively soon. I know I've made claims already regarding when I was intending to upload things over on the Lazarus forums (which I certainly have failed to live up to ) but... I don't really care? Considering that this is all work I'm doing for zero dollars, and all. Good things come to those who wait, as they say.

[Jeroen]

That certainly is waaaaaaay cool! No worries about things taking time - I know all about that myself. Let us know when the exe is available so we can play with this new stuff! Keep up the good work!
