• 如何在开放式GL中拆解地图
原标题:How to disable mipmaps in OpenGL

I am making 2D sprite engine in OpenGL and I want to disable mipmaps, as I do not need them.

我请我发言:

glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, internal->internal_w, internal->internal_h, 0, GL_RGBA, GL_UNSIGNED_BYTE, internal->data);
RenderWithThisTexture();

我 go白,但当我说:

gluBuild2DMipmaps(GL_TEXTURE_2D, GL_RGBA, internal->internal_w, internal->internal_h, GL_RGBA, GL_UNSIGNED_BYTE, internal->data);
RenderWithThisTexture();

下面是经过适当修改的。

我曾指出,这可能是因为能够绘制地图,但不幸的是,我会发现,我会如何消除这些地图。

我想坚持开放的GL 1.1(而不是OGL2.0或以上代码)。

最佳回答
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);

这应当是违约。 确保在有些地方不将其改为
