Update: Not so easy, unfortunately. Did a quick test and it is VERY fast, but looks horrible. Looked again at the speccy version and it seems that they don't do something so simple. Have a look at this screenshot: http://www.defence-force.org/ftp/forum/3Dthings/speccyframecrobra.PNG First, it is di...

Greetings. Some advances (small, but important, imho). Tweaked the contol panels and now they are more usable. Also started coding their behaviour, so shields, speed and missiles (including all the locking sequence), radar and scanner are all working. Thanks to Twilighte for his impressive work in t...

Not sure about what I will say here, as I am talking by memory and all this was a long time ago. Anyway I owned an Oric-1 which was converted to an Atmos with a kit that existed then. The thing is that the keyboard could not be replaced directly, IIRC. I remember they had to carry my Oric to an elec...

Greetings again. Twilighte has sent me yet another version (nearly definite, I'd say). Now there are control panels both above and below the screen and they are INCREDIBLE. I integrated them with the current version and here is an screenshot: http://www.defence-force.org/ftp/forum/3Dthings/intro-new...

Ok, thanks to the magic of Twilighte, we have a first approach to a really good frame for this game. Have a look: http://www.defence-force.org/ftp/forum/3Dthings/newframe-twi.PNG I know the scanner where the planet position is drawn is destroyed (need some tweak in the code and also in the graphic),...

Man you are incredible. That may be true for this scorepanel but it means 'diddly squat' as you then disect and remove most of the scorepanel graphics :( Didn't meant to remove your ideas at all. I think that simply placing the arc some 4 pixels below the radar display, something similar to the NES...

Man you are incredible. I like the screenshot a lot, indeed. Hard to recognize an Oric there. I think you'd be glad to read the above post, as I mention that there is no need to have so many controls for this version, so there is much more room for doing nice tricks :) However, I have some comments ...

Chema, i notice that the right line marking the right border of the play area is one away from the left edge of the byte. Is this intentional? I will assume (for now) it was not. However the idea of placing a single pixel wide black outline around the play area is a good one, since it isolates acti...

Thanks!

BTW, did you notice the "extra pixel" bug in the line routine? Any clue?

That does look rather fab, and it all seems to be coming together. I wonder if the same graphic technique used in IM and Otype could be adapted to the score panel in Elite? Let me know if you want me to design something for you Chema?, i am still very busy with IM but i'm sure i can find some time ...

Ok, I noticed it has been a long time since the last screenshots, so here you are. Notice I am also playing with the coloured frame, now trying to see how a combination of colours at alternating scans could work in the radar display. However, I am somehow color-blind :? , so I will need some hints t...

Greetings. Some advance. I finished implementing the 1st technique above for backface culling. That is: using pre-calculated normals and rotating them. After that process, the dot product with the vector from the point-of-view with the object is calculated and the sign of the z-component decides whe...

Yeah, that might be the point where backface culling and drawing filled polygons converge (?). Actually that is a good idea. Another method to test... I also was thinking that most of the polygons are rather small. Usually their width or heigth is below 1/4th of the screen, so most of the times the ...

Greetings. Ok. I come here today with a request for a brainstorm :) After talking with Dbug in the chat yesterday, we thing that the best method to use is checking the vertex order using the cross product (basically the first method, but only getting the Z coordinate of the cross product). You need ...

New log. Nothing really new. Have been working on a more accurate ship control. In fact I just duplicated the tables and patched a routine so the ship you control now rotates in steps of 1 degree, but keeping the key pressed speeds up the rotation. Also added some kind of damping effect, so it looks...
