GemException changes not approved by MSVC 2003
by chris clepper 14 Sep '06

14 Sep '06

I haven't updated the Base classes in about two weeks and the change made to GemException has made MSVC very unhappy. It throws a warning about public std::exception for each and every class compiled. The warning is C4275: no dll-interface class 'exception' used as base for dll-interface class 'GemException'. Webpage here: http://msdn2.microsoft.com/en-us/library/3tdb471s.aspx I have no idea what this really means. MS doesn't have a runtime exception for use with DLLs? Should I just do the pragma to shut the warning off? cgc

noise problem with glsl
by cyrille henry 14 Sep '06

14 Sep '06

hello, i received my orange book few days ago. so i'm back with glsl. i give up for now with multitexture. my aim was to use 1 noisy texture to distord the other one. i discover the noise fonction of glsl, but i've got problem, trying to use it. by example, a simple vertex shader like this : void main(void) { vec4 v = vec4(gl_Vertex); vec4 pos = gl_ModelViewMatrix * v; float LightIntensity = max(dot(normalize(vec3(0.,3.,3.) - pos.xyz), gl_Normal), 0.0); gl_FrontColor = gl_Color * LightIntensity; v.x += 0.1 * noise1(v); // commenting this line // make the shader to work gl_Position = gl_ModelViewProjectionMatrix * v; } gives me error : Vertex info ----------- <stdlib>(3998) : warning C7011: implicit cast from "int" to "float" <stdlib>(3998) : warning C7011: implicit cast from "int" to "float" (same errore with noise1, noise2, noise3.., whatever vecter size of the input parametter) does anyone know where the problem came from? what should i try? etc should i ask this question in an other mailling list (as i don't think it's a gem problem)? does anyone interested in my working example: sould i upload my patch somwhere? thanks Cyrille

osx crashes with gem from extended
by Tim Blechmann 13 Sep '06

13 Sep '06

hi all, today a friend of mine contacted me, because he has some problem with a gem patch. the patch is reported to work fine for some time, but after some time, it crashed with "vm_allocate failed (errorcode=3)". i don't know exactly, what the patch is doing, but it's somehow displaying multiple videos in different ways ... the gem version is from a pd-extended-0.39 package ... any idea, what could cause this crash? thanks ... tim -- tim(a)klingt.org ICQ: 96771783 http://www.mokabar.tk All we composers really have to work with is time and sound - and sometimes I'm not even sure about sound.

./configure doesn't detect avformat.h
by Hans-Christoph Steiner 13 Sep '06

13 Sep '06

On a plain Debian/etch/x86 box, I ran this command: ./configure --with-pd=/home/pd/auto-build/pd-extended/pd && make And it died looking for avformat.h, which was not install. Perhaps ./ configure should look for that file too. I am installing libavformat.h and carrying on. .hc ------------------------------------------------------------------------ There is no way to peace, peace is the way. -A.J. Muste

multitexture unit shader issues
by chris clepper 05 Sep '06

05 Sep '06

It looks like the key to getting shaders working with multiple texture units has to do with the texture target geometry knowing about the proper texture coordinates. A while ago SetVertex() was modified to set up the first 8 multitexture coordinates. Right now only square uses this call as far as I can tell. All of the Geos could be changed to use this function or a different SetTexCoord() one could be made to deal with the glMultiTexCoord2fARB calls. The code would be pretty ugly if each Geo added 7 more texture calls per vertex otherwise. Also, I quickly added a 'texunit' message and glActiveTextureARB() call the pix_texture which allows for the use of multiple texture units in shaders without pix_multitexture. I don't know if this is duplicate work or goes against plan, but it seems pretty straightforward when working with shaders. cgc
