Drawing points

[Hey]

Hello everyone, I am trying to draw around 10,000 points. So instead of calling window.draw(...) 10,000 times I was thinking of putting into a vertex array, and drawing with single draw call.

But how can I increase the point size? I know the OpenGL function that does this, which is glPointSize(...). But is there another way?

You can use quads instead of points.

SFML doesn't let you draw bigger points directly.

Multiple options:

• sf::VertexArray: Draw triangles or quads if the shape is ok
• sf::VertexArray: Draw multiple points per point
• sf::VertexArray: Use a texture for a point, and draw it with quads (4 vertices per point)
• sf::RenderTexture, sf::Texture, sf::Sprite: Draw the points once to a render texture, build a sprite from it and draw that
