I'm new in Manim and I'm trying to scale my plane because the grid and vectors get out under the following linear transformation
class LinearTransformationSceneExample(LinearTransformationScene):
def __init__(self, **kwargs):
LinearTransformationScene.__init__(
self,
show_coordinates=True,
leave_ghost_vectors=True,
*kwargs
)
def construct(self):
matrix = [[9, 0], [-3/2, 3/2]]
self.apply_matrix(matrix)
self.wait()
I tried many things, but withput any success. However, the closest I have come has been with the following code, but the linear transformation is applied in the center of the plane
class LinearTransformationSceneExample(LinearTransformationScene):
def __init__(self, **kwargs):
LinearTransformationScene.__init__(
self,
show_coordinates=True,
leave_ghost_vectors=True,
background_plane_kwargs = {
"x_range" : [-10,10],
"y_range" : [-1,10],
"x_length" : 14.2,
"y_length" : 8
},
foreground_plane_kwargs = {
"x_range" : [-10,10],
"y_range" : [-1,10],
"x_length" : 14.2,
"y_length" : 8
}
)
def construct(self):
vec = Vector([-1,1])
vec.set_color(PURPLE)
self.add_vector(vec)
matrix = [[9, 0], [-3/2, 3/2]]
self.apply_matrix(matrix)
self.wait()
If you can follow the idea of the code above it'd be great, but it's not really necessary
