I should have known better, after all, I am the one who wrote those macros :oops: Well, technically the operation operates on the angle in radians... Basically, the DEG2RAD multiplication is pre-computed for the degree based function :wink: And, yeah it is faster to use fsincos(degree) rather than c...

Thanks BlueCrab, I just went ahead and committed the reformatted code. Should be good to go!

I double checked this morning, and yes the rotations have been corrected in the current commit, by simply reversing the sign of the rotation angle as mentiond; trick is OpenGL rotations are counter-clockwise, and the mat_rotate code in KOS rotates clockwise :o . The texture used here is taken from t...

1. Sorry mate that's just how I roll :lol: 2. I need to re-configure my PC chain ATM, I will try to get into it today. 3. The DMA Vertex Transfer is still experimental, and thus disabled by default. The current implementation is using blocking DMA and shows faster throughput on emulator, but is not ...

Thanks again BlueCrab! Things are definitely in decent shape, I tested all of the changes on real hardware with no problems. But I just realized that my commit from today is not stylized as before, I seem to have lost the tool you sent me to format the code.. I took a quick look through our PM's, bu...

Just letting you guys know that I have made a decent update to the API today, as usual, get it here: http://sourceforge.net/p/cadcdev/libgl/ci/master/tree/ A quick list of what is new: +Added Texture Format Conversion for glTexImage2D, allowing many more texture types to be uploaded -Before, the API...

BlueCrab-
I just made a commit to libgl, and I notice that you have changed the kos-ports structure a bit since the last time I committed.
Can you take a quick look, and tidy things up if need be?
Thanks in advance.

BTW I didn't check your vertex transformation assembly code in detail, but I think you didn't implement texture matrices. Maybe they would allow you to apply a cool effect. It is a hit on performance, but I am working on adding texture matrices into OpenGL. But yes, in fact, this is a nice solution...

A crude method I use for testing function efficiency is to run a loop say 10,000,000 times, and measure CPU time spent. Within that loop, call the function in question; i.e. glRotatef(...). If your method uses 900 msec while previous method uses 1000 msec, you have made solid progress... :lol: Yeah...

Heh, on Windows this is a non-issue
But on Linux, yes, the FS is case sensitive. Hmmz, should be an easy enough fix

MisterDave - Yes, Arrays are more able to be optimized for, and perform much better in my API as a result. In fact, you can see that I wrote 2 separate clipping algorithms: gl-clip.c and gl-clip-arrays.c, with Arrays being the faster Mode compared to Immediate Mode. There are a few examples included...

Thanks man!
That vid is an old build by now.
Here is a more current build, I posted on another thread here...

Yes, I am testing hoard size :lol: It will depend on Map Size, Graphic Options, and weather or not 2 player mode is active. Light Maps = 2x Render BSP Geometry. Stencil Shadows = 2x Render Per Model. 2 Player Mode = 2x Render Everything. Light Maps Off + Stencil Shadows Off Might Be Possible to have...

IMO that seems a bit too colorful for a Zombie setting, so here is another map.
Adding PVR Fog helps set the mood

Youll probably have to wait forever, lol, I seriously doubt M$ will achieve 100% compatibility. They are emulating the 360 games, have you ever seen an emulator that is 100% compatible? IMO, PS4 lacks the power to emulate the unique PS3 Cell CPU, a Sony rep said "if it was easy, we’d have done ...

2015 games played: - Box Boy - Crypt of the NecroDancer - Freedom Planet 2015 games to play (not counting games that aren't out yet): - Axiom Verge - Batman: Arkham Thingie - Odallus (if I can get it working on a Mac) - Titan Souls Making great use of that Retina iMac and Radeon 295X :oops: I didnt...

A quick video with the option to change Shadow Quality between Off, Fast, and Stencil. Off is obvious. Fast uses a pre-tessellated circle that is actually a non-textured mesh, using alpha blending to achieve the "shadow". Stencil again is non-textured alpha blended, but uses the model geom...

LOLz. Very interesting idea! I never thought I would hear "spherical harmonics" and "Dreamcast" in the same sentence :lol: I have believed that spherical harmonics is the understanding of how light bounces off of surfaces, thus indirectly lighting reflected surfaces. Or am I conf...

Looks cool, I like the variance in pitch, yaw, and roll you achieve with your tracks. But I keep thinking it would look better with the "sprites" facing in the direction of their surface normal, instead of facing the camera. I am curious how you handle batching your sprites, do you use glB...
