Thanks for the report, could You post a small test program where these errors are visible? If You are using IrrNX did You check out the latest version from cvs?
The fullscreen mode where only the upper-left corner is used
might occure if You're switching to a resolution Your OpenGL driver is not supporting.
If You're using an unpatched irrlicht v0.7 and are using my changes for the materialrenderers here's a patch for CVideoOpenGL.cpp
Patch for 2D Image problem:
search in all methods
draw2DImage where the 2D render states are set. Then cut the line with
setTexture( ...... ); and past it after the block where the renderstate is set
Example:
the original function look like this
Code: Select all
void CVideoOpenGL::draw2DImage(video::ITexture* texture, const core::position2d<s32>& pos, const core::rect<s32>& sourceRect, const core::rect<s32>* clipRect, SColor color, bool useAlphaChannelOfTexture)
{
....
// ok, we've clipped everything.
// now draw it.
setTexture(0, texture);
glColor4ub(color.getRed(), color.getGreen(), color.getBlue(), color.getAlpha());
if (useAlphaChannelOfTexture)
setRenderStates2DMode(false, true, true);
else
setRenderStates2DMode(false, true, false);
core::rect<s32> poss(targetPos, sourceSize);
...
}
change it to look like this:
Code: Select all
void CVideoOpenGL::draw2DImage(video::ITexture* texture, const core::position2d<s32>& pos, const core::rect<s32>& sourceRect, const core::rect<s32>* clipRect, SColor color, bool useAlphaChannelOfTexture)
{
....
// ok, we've clipped everything.
// now draw it.
if (useAlphaChannelOfTexture)
setRenderStates2DMode(false, true, true);
else
setRenderStates2DMode(false, true, false);
setTexture(0, texture);
glColor4ub(color.getRed(), color.getGreen(), color.getBlue(), color.getAlpha());
core::rect<s32> poss(targetPos, sourceSize);
...
}
Patch for Shadows (only minor changes,I don't remember exactly what changed, sorry)
Code: Select all
//! Draws a shadow volume into the stencil buffer. To draw a stencil shadow, do
//! this: Frist, draw all geometry. Then use this method, to draw the shadow
//! volume. Then, use IVideoDriver::drawStencilShadow() to visualize the shadow.

LastMaterial.MaterialType >= 0 && LastMaterial.MaterialType < (s32)MaterialRenderers.size())
{
MaterialRenderers[LastMaterial.MaterialType]->OnUnsetMaterial();
ResetRenderStates = true;

glStencilOp(GL_KEEP, GL_KEEP, GL_INCR);
glCullFace(GL_BACK);
glBegin(GL_TRIANGLES);
s32 i;
for(i = 0; i < count; ++i)
glVertex3f(triangles[i].X, triangles[i].Y, triangles[i].Z);
glEnd();

Thanks again for the report.
I'm hoping that with the new OGL 2.0 coming out they'll get an update
