Re: [no bug] Bug in COGLES2MaterialRenderer

It has crashed because of this issue. I compiled it with GCC with debug symbols and identified the Problem with gdb. BTW: You can not know if every compiler with every settings does evaluate the disjunctions as you describe.

[no bug] Bug in COGLES2MaterialRenderer

Hi, there's a bug in COGLES2MaterialRenderer.cpp in both implementations of setPixelShaderConstant: original code: if(index < 0 || UniformInfo[index].location < 0) return false; If index is <0 it will crash because of UniformInfo[index]. Please replace it (both times) with (or similar):     if(index...

[fixed]Empty ListBox Bug when pressing end -> any character

There's a bug with empty ListBoxes: If you press the end button and after that any character button in a focused empty ListBox it will crash. This ist because of the following code in CGUIListBox.cpp (CGUIListBox::OnEvent) :                 if (Selected >= (s32)Items.size())                     Sele...

Re: u16 on Android propably signed

Ok I have tested it. Surprisingly it is not signed.
But why does it behave this way on android? Has anybody an idea?

u16 on Android propably signed

I noticed when I created a SMeshBuffer (16 Bit Indices) with 256^2=65536 Vertices (256x256 regular grid) that it worked well on Linux but not on Android. After some experimenting I noticed that the maximum amount of Vertices in a regular grid is 181^2 (181x181 grid), if u16 is signed this would be t...

Re: Ogles/Android: TRANSPARENT_ALPHA_CHANNEL_REF Material co

I don't think so.
The OpenGL driver uses also textures and colors.
This makes also sense because if you don't want to use colors, just use white and you can get the same behaviour than without colors.

[fixed]Ogles: TRANSPARENT_ALPHA_CHANNEL_REF Material colors

Hi,

I noticed that with EMT_TRANSPARENT_ALPHA_CHANNEL_REF the colors in the SMaterial are ignored.
This can be fixed by replacing:

Code: Select all

glTexEnvi(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_REPLACE);
with:

Code: Select all

glTexEnvi(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_MODULATE);
in the COGLESMaterialRenderer.h

Re: slerp Bug

That's a good idea, but unfortunately I wasn't able to get ndk-gdb running. I'm using the internal sensors of my Nexus 7 for both rotations, so I can't test it on my pc.

Re: slerp Bug

I used slerp for sensor fusion to interpolate between a slow changing reference rotation and a fast changing gyroscope rotation (which has an accumulating error) to eliminate the error. For testing purposes I used a predefined rotation in exchange for the gyrosope output which converges then to the ...

slerp Bug

Hi, I noticed that quaternion::slerp may calculate a not normalized quaternion (because of rounding errors and epecially in the lerp case). In my case the slerp result was sometimes up to 10° off. After I added the normalization the problem disappeared: Please change:        if (angle <= (1-threshol...

Re: Weird error on Android 2.3 (Samsung Galaxy Y)

Thanks for your reply. egl version 1.4 is used according to the logcat. When I use ogles 1 I don't get the error in the logcat, but nothing is displayed on the screen except of the background color. (With ogles2 I get also only a blank screen with the background color and of course the error in the ...

Re: Useful modifications to the android port (ogles-branch)

I now implemented the CursorControl for Android, because I think it should be there for compatibility reasons (most software will propably not check if the CursorControl is NULL, for example the FPS Camera). Unfortunately it's afaik not possible to change the visibility and cursor position if an ext...
