Question

我尝试使用OpenGL ES 2.0在Android NDK程序中加载和显示纹理。

图像加载正在运行，但我尝试使用glTexImage2D初始化纹理，但它总是抛出错误：distrib / android-emugl // host / libs / Translator / GLES_V2 // GLESv2Imp.cpp：glTexImage2D： 1883错误0x501

我在glTexImage2D上遇到问题

glTexImage2D（GL_TEXTURE_2D，0，texture [0] .bpp / 8，texture [0] .width，texture [0] .height，0，texture [0] .type，GL_UNSIGNED_BYTE，texture [0] .imageData） ;

我使用128x128图像尺寸。

请帮助我一些。

代码类似于：

你为glTexImage2D提供的参数似乎是错误的。

glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, texture[0].width, texture[0].height, 0, GL_RGBA, GL_UNSIGNED_BYTE, (GLvoid*)texture[0].imageData);

glTexImage2D使用OpenGL ES 2.0抛出错误0x501 Android NDK程序
