Generate mesh object

OpenGL OpenGL: Advanced Coding

Hi,

I’m trying to generate a plane using 100 x 100 planes, and tesselate then on a big plane so that I can change its own texture, but I must generate the same mesh everytime I want to send it to glVertex, so sending 100 x 100 vertices everytime is very slow, is there nay other way to generate the texture only once and the send it everytime?

this is what I’m using:

DrawMultiRect2D(X, Y, Width, Height: Double);
var
  X2, 
  Y2: Double;
  x2, y2: Integer;
begin
  X1 = Width / 2;
  Y1 = Height / 2;

  glEnable(GL_TEXTURE_2D);

  for y2 = -50 to 50 do
  for x2 = -50 to 50 do
  begin
    glBindTexture(GL_TEXTURE_2D, 1);
    glBegin(GL_QUADS);
      glTexCoord2f(0, 0); glVertex2f((x2)*X1,      (y2)*Y1);
      glTexCoord2f(1, 0); glVertex2f((x2)*X1 + X1, (y2)*Y1);
      glTexCoord2f(1, 1); glVertex2f((x2)*X1 + X1, (y2)*Y1 + Y1);
      glTexCoord2f(0, 1); glVertex2f((x2)*X1,      (y2)*Y1 + Y1);
    glEnd();
  end;

  glDisable(GL_TEXTURE_2D);
end;

is there any other way?
