I am trying to load and draw texture on a polygon. Here are the two functions I have written:
textures = []
def loadBitmap(fileName):
global textures
#load in the file
textureSurface = pygame.image.load(fileName)
textureData = pygame.image.tostring(textureSurface, "RGBX", 1)
#Bind it to a texture
textures = glGenTextures(2)
glBindTexture(GL_TEXTURE_2D, textures[0])
glTexImage2D( GL_TEXTURE_2D, 0, GL_RGBA, textureSurface.get_width(), textureSurface.get_height(), 0,
GL_RGBA, GL_UNSIGNED_BYTE, textureData )
def drawBitmap(x,y,width,height):
global textures
glBindTexture(GL_TEXTURE_2D, textures[0])
glBegin(GL_QUADS)
glTexCoord2i(0, 0); glVertex2i(x, y)
glTexCoord2i(1, 0); glVertex2i(x+width, y)
glTexCoord2i(1, 1); glVertex2i(x+width, y+height)
glTexCoord2i(0, 1); glVertex2i(x,y+height)
glEnd()
and in the draw function I am calling 'drawBitmap(400,400,256,256)'
the texture file is of 256x256 resolution.
The application I am writing here is 2D.
There is no depth test. It's disabled.
I am getting a gray colored square instead of textured one...?
I am using selection/picking on mouse down.
When ever I click the gray square flicks...? Rest of the drawing is having no problem at all.
In 'loadBitmap' function if I try to load a single texture using 'textures = glGenTextures(1)' I get an error. How do I solve this...?
Best regards.
Cheers
