Package: stormbaancoureur
Version: 2.1.6-3
Followup-For: Bug #1014937
X-Debbugs-Cc: nils+debian-report...@dieweltistgarnichtso.net
I haveinvestigated the source package of stormbaancoureur.
The file src-common/ogl.cxx contains the shadow rendering functionality.
It also contains a check for when exactly shadow rendering is enabled:
--- 8< --- snip --- 8< ---
/*
* This helper function checks wether we have all req'd extensions for shadow
mapping
*/
bool OglCanDoShadowing(void)
{
if (getenv("PLODE_NO_SHADOWS")) return false;
const char *vers = (const char*) glGetString(GL_VERSION);
const char *rend = (const char*) glGetString(GL_RENDERER);
fprintf(stderr, "OpenGL is version %s\n", vers);
fprintf(stderr, "OpenGL renderer %s\n", rend);
const char *exts = (const char*) glGetString(GL_EXTENSIONS);
//fprintf(stderr, "OpenGL has extensions %s\n", exts);
if (!strstr(exts, "GL_ARB_multitexture")) return false;
if (!strstr(exts, "GL_ARB_depth_texture")) return false;
if (!strstr(exts, "GL_ARB_shadow")) return false;
if (!strstr(exts, "GL_EXT_framebuffer_object")) return false;
if (!strstr(exts, "GL_ARB_vertex_shader")) return false;
if (!strstr(exts, "GL_ARB_fragment_shader")) return false;
if (!strstr(exts, "GL_ARB_shader_objects")) return false;
return true;
}

The Irrlicht engine manages to do bug-free realtime shadows on the same GPU.
Therefore, I assume that this issue can be worked around relatively easily.
