Canvas Textures

#1 Post by Keith Baxter » Thu Apr 29, 2021 9:52 am

Hi,

For those that want to play with canvas_draw() textures, I have done some simple code to achieve that. Lets see you creations.
texture_carbon_clasic1.png

Code: Select all

---texture_carbonfiber1
my_canvas= canvas_add(0,0,800,500)

canvas_draw(my_canvas,function()
  _rect(0,0,800,500)
  _fill("#2a2a2a")

  for i = 0,162 do  
   _move_to(0+(i*8),0)
   _line_to(0,0+(i*8))
   _stroke("#515151",1)
  end  
end)
texture_carbon_mat2.png

Code: Select all

---texture_carbonfiber2

my_canvas= canvas_add(0,0,800,500)

canvas_draw(my_canvas,function()
  _rect(0,0,800,500)
  _fill("#2a2a2a")

  for i = -1,133 do 
    for i2 = -1,83 do 
      _rotate(45,3+(i*6),3+(i2*6))
      _rect(5+(i*6),0+(i2*6),6,6)  
      _stroke("#515151",0.5)   
     _rotate(-45,3+(i*6),3+(i2*6))
    end
  end   
end)
texture_carbon_cross3.png

Code: Select all

---texture_carbonfiber3
my_canvas= canvas_add(0,0,800,500)

canvas_draw(my_canvas,function()
  _rect(0,0,800,500)
  _fill("#2a2a2a")

  for i = -1,100 do 
    for i2 = -1,62 do 
      _rotate(45,2+(i*8),4+(i2*8))
      _rect(5+(i*8),0+(i2*8),8,8)  
      _stroke("#515151",0.5)   
      _rotate(-45,2+(i*8),4+(i2*8))
    end
  end   
end)
texture_carbon_mesh4.png

Code: Select all

---texture_carbonfiber4
my_canvas= canvas_add(0,0,800,500)

canvas_draw(my_canvas,function()
  _rect(0,0,800,500)

  for i = 0,100 do 
    for i2 = 0,62 do 
     _rotate(45,2+(i*8),4+(i2*8))
     _rect(5+(i*8),0+(i2*8),6,6)  
     _stroke("#515151",0.5)   
     _rotate(-45,2+(i*8),4+(i2*8))
    end
  end   
end)
texture_carbon_diamond5.png

Code: Select all

---texture_carbonfiber5
my_canvas= canvas_add(0,0,800,500)

canvas_draw(my_canvas,function()
  _rect(0,0,800,500)
  _fill("#2a2a2a")

  for i = 0,80 do 
    for i2 = 0,50 do 
      _rotate(45,3+(i*10),3+(i2*10))
      _rect(5+(i*10),0+(i2*10),6,6)  
      _stroke("#515151",1)   
      _rotate(-45,3+(i*10),3+(i2*10))
    end
  end   
end)

ahah, challenge accepted!
I needed to create an image for the rice grain shape in Skinman though.
image.png

Code: Select all

texture_size_X=800
texture_size_Y=500
size_X=11
size_Y=34
scale=1
img_add_fullscreen("background color 1x1.png")
for i=0,(texture_size_X/(30*scale)) do
    for j=0,(texture_size_Y/(35*scale))  do
        rotate(img_add("grain de riz.png",i*30*scale,j*35*scale,size_X*scale,size_Y*scale),45-(90)*(j%2))
    end
end
same with scale=0.2

Nice one Jacques,

I am sure we will come up with a bunch of stuff for all.

Well, it's just for fun, not sure of the real advantage of creating textures "on the fly" by using png images, as it can't be used afterwards to populate complex shapes.
By using canvas_draw, one can augment the fun, though..

Code: Select all

canvas_id = canvas_add(0, 0, 800, 500, draw_callback)

k=10
step=10
dir="up"
-------------------
function animate()
canvas_draw(canvas_id, function()
	 -- Create a pulsating circle
	if (k>300 and dir=="up") then 
    		step=-10
    		dir="down"  	
	end
	if k<=10 and dir=="down" then
    		step=10 
    		dir="up"
	end
	k=k+step
	_circle(400,250,k)
	_stroke("red", 4)
	_circle(400,250,k)
	_fill_img("texture_grain de riz.png", 0, 00, 800, 500)
end)
end

It would be nice to be able to fill a polygon with one of these textures.

This is the instrument panel in the TorqueSim SR20 G1000 The texture looks square checkered.

I will do that one next then see if I can reproduce a brush aluminum. I suspect that the CPU will take quite a hit with that one.

When looking at the real SR20 dashboard pictures, the texture looks more to a grained texture.

IMHO, there is absolutely no point of trying to create a texture with canvas_draw() if it’s to be used for a static panel like for the SR20.

Skinman gives you definitely a more flexible approach in that case.
Done in 5 (five) minutes:

and once the texture pattern is done, you can adjust it

Granted, canvas_draw() is unbeatable when it's time for drawing map features (like you did) or ND dynamic display, but vector images rule when it's about textures. ;)

And to have a brushed metal aspect, just search for "seamless textures" on the Net, and add it to the textures folder of skinman.
Add a metal effect light in one click and voilà!

Haha,

The big texture vs canvas fight ;)
In the end both have there own strengths and weaknesses, and luckily you can combine them quite easily.
