sourcepub fn new_p2(context: &Context, mode: VerticesMode, data: &[&P2]) -> Primitive
pub fn new_p2(context: &Context, mode: VerticesMode, data: &[&P2]) -> Primitive
Provides a convenient way to describe a primitive, such as a single
triangle strip or a triangle fan, that will internally allocate the
necessary AttributeBuffer
storage, describe the position
attribute with a Attribute
and upload your data.
For example to draw a convex polygon you can do:
VertexP2 triangle[] =
{
{ 0, 300 },
{ 150, 0, },
{ 300, 300 }
};
prim = primitive_new_p2 (VERTICES_MODE_TRIANGLE_FAN,
3, triangle);
primitive_draw (prim);
The value passed as n_vertices
is initially used to determine how
much can be read from data
but it will also be used to update the
Primitive
<structfield>
n_vertices</structfield>
property as if
Primitive::set_n_vertices
were called. This property defines
the number of vertices to read when drawing.
The primitive API doesn’t support drawing with sliced
textures (since switching between slices implies changing state and
so that implies multiple primitives need to be submitted). You
should pass the TextureFlags::NoSlicing
flag to all textures that
might be used while drawing with this API. If your hardware doesn’t
support non-power of two textures (For example you are using GLES
1.1) then you will need to make sure your assets are resized to a
power-of-two size (though they don’t have to be square)

Provides a convenient way to describe a primitive, such as a single

{ 150, 0, 0x00, 0xff, 0x00, 0xff },

) -> Primitive
sourcepub fn copy(&self) -> Option<Primitive>
pub fn copy(&self) -> Option<Primitive>
Makes a copy of an existing Primitive
. Note that the primitive
is a shallow copy which means it will use the same attributes and
attribute buffers as the original primitive.
Returns
the new primitive
sourcepub fn draw<P: Is<Framebuffer>>(&self, framebuffer: &P, pipeline: &Pipeline)
pub fn draw<P: Is<Framebuffer>>(&self, framebuffer: &P, pipeline: &Pipeline)
Draws the given self
geometry to the specified destination
framebuffer
using the graphics processing state described by pipeline
.
This drawing api doesn’t support high-level meta texture types such
as Texture2DSliced
so it is the user’s responsibility to
ensure that only low-level textures that can be directly sampled by
a GPU such as Texture2D
, TextureRectangle
or Texture3D
are associated with layers of the given pipeline
.
framebuffer

pub fn first_vertex(&self) -> i32
sourcepub fn indices(&self) -> Option<Indices>
pub fn indices(&self) -> Option<Indices>
Returns
the indices that were set with
Primitive::set_indices
or None
if no indices were set.
pub fn mode(&self) -> VerticesMode
sourcepub fn n_vertices(&self) -> i32
pub fn n_vertices(&self) -> i32
Queries the number of vertices to read when drawing the given
self
. Usually this value is implicitly set when associating
vertex data or indices with a Primitive
.
If Primitive::set_indices
has been used to associate a
sequence of Indices
with the given self
then the
number of vertices to read can also be phrased as the number
of indices to read.
To be clear; it doesn’t refer to the number of vertices - in terms of data - associated with the primitive it’s just the number of vertices to read and draw.
Returns
The number of vertices to read when drawing.
sourcepub fn set_attributes(&self, attributes: &[&Attribute], n_attributes: i32)
pub fn set_attributes(&self, attributes: &[&Attribute], n_attributes: i32)
Replaces all the attributes of the given Primitive
object::
attributes
an array of Attribute
pointers
n_attributes
the number of elements in attributes
pub fn set_first_vertex(&self, first_vertex: i32)
sourcepub fn set_indices(&self, indices: &Indices, n_indices: i32)
pub fn set_indices(&self, indices: &Indices, n_indices: i32)
Associates a sequence of Indices
with the given self
.
Indices
provide a way to virtualize your real vertex data by
providing a sequence of indices that index into your real vertex
data. The GPU will walk though the index values to indirectly
lookup the data for each vertex instead of sequentially walking
through the data directly. This lets you save memory by indexing
shared data multiple times instead of duplicating the data.
The value passed as n_indices
will simply update the
Primitive
<structfield>
n_vertices</structfield>
property as if
Primitive::set_n_vertices
were called. This property defines
the number of vertices to draw or, put another way, how many
indices should be read from indices
when drawing.
The Primitive
<structfield>
first_vertex</structfield>
property
also affects drawing with indices by defining the first entry of the
indices to start drawing from.
indices
A Indices
array
n_indices
The number of indices to reference when drawing
pub fn set_mode(&self, mode: VerticesMode)
sourcepub fn set_n_vertices(&self, n_vertices: i32)
pub fn set_n_vertices(&self, n_vertices: i32)
Specifies how many vertices should be read when drawing the given
self
.
Usually this value is set implicitly when associating vertex data
or indices with a Primitive
.
To be clear; it doesn’t refer to the number of vertices - in terms of data - associated with the primitive it’s just the number of vertices to read and draw.
n_vertices
The number of vertices to read when drawing.
