i wanna use one pic for the whole terrain.but why does it look so weird?? i wanna texture this pic: and it looks like this: why?? here is the code:
float xTexture = 0.0f;
float yTexture = 0.0f;

for(y=1; y<heightMapHeight-1; y++)
if(renderMode==RENDER_FILLED || renderMode==RENDER_TEXTURED)

	//Render the row as a triangle strip

	for(x=0; x<heightMapWidth-1; x++)
	glTexCoord2f(xTexture, yTexture);
	glTexCoord2f((xTexture + (1/heightMapWidth)), yTexture);
	glTexCoord2f(xTexture, (yTexture + (1/heightMapHeight)));
	glTexCoord2f((xTexture + (1/heightMapWidth)),( yTexture + (1/heightMapHeight)));
	xTexture += (1.0f/heightMapWidth);

xTexture = 0.0f;
yTexture += (1.0f/heightMapHeight);

Looks like your texture coordinates are screwed up. Haven''t looked at your code, but I''m guessing that''s why it looks funny.

Move your glTexCoord2(...);''s around and keep testing it you will find the correct order remember that you are useing a TRIANGLE_STRIP : ) .
