为什么这段代码不会在 pyopenGL 中显示我的纹理
我正在尝试为我进行多通道纹理工作，但现在我可以进行简单的纹理工作，任何人都可以通过以下代码来了解发生了什么。此示例仅将多边形显示为白色，而不是有纹理。
def loadTexture(name):
img = PIL.Image.open(name) # .jpg, .bmp, etc. also work
img_data = numpy.array(list(img.getdata()), numpy.int8)
id = glGenTextures(1)
glPixelStorei(GL_UNPACK_ALIGNMENT,1)
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP)
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP)
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR)
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR)
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, img.size[0], img.size[1], 0, GL_RGB, GL_UNSIGNED_BYTE, img_data)
return id
......
tex = loadTexture(/foobar.png)
glMatrixMode(GL_MODELVIEW)
glLoadIdentity()
glTranslate(0.0, 0.0, -600)
glScale(50.0, 50.0, 50.0)
glRotate(90, 0.0, 0.0, 0.0)
glEnable(GL_TEXTURE_2D)
glBindTexture(GL_TEXTURE_2D, tex)
glBegin(GL_TRIANGLES)
....
glEnd()
I'm trying to get multipass texturing work for me but right now i can get simple texturing to work, can anybody spor whats going wring with the following code. This examples just shows the poly as white, rather than textured.
def loadTexture(name):
img = PIL.Image.open(name) # .jpg, .bmp, etc. also work
img_data = numpy.array(list(img.getdata()), numpy.int8)
id = glGenTextures(1)
glPixelStorei(GL_UNPACK_ALIGNMENT,1)
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP)
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP)
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR)
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR)
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, img.size[0], img.size[1], 0, GL_RGB, GL_UNSIGNED_BYTE, img_data)
return id
....
tex = loadTexture(/foobar.png)
....
glMatrixMode(GL_MODELVIEW)
glLoadIdentity()
glTranslate(0.0, 0.0, -600)
glScale(50.0, 50.0, 50.0)
glRotate(90, 0.0, 0.0, 0.0)
glEnable(GL_TEXTURE_2D)
glBindTexture(GL_TEXTURE_2D, tex)
glBegin(GL_TRIANGLES)
....
glEnd()

设置纹理参数或上传数据时必须调用glBindTexture(GL_TEXTURE_2D, id)：
You must call glBindTexture(GL_TEXTURE_2D, id) when you are setting texture parameters or uploading data:
